I am trying to mix both xml and Java Configuration.
I have a spring-security.xml resource that I import in my application boot.
Say this was a part of the initial xml:
<bean id="ldapContextSource" class="org.springframework.ldap.core.support.LdapContextSource">
<property name="url" value="${ldap.url}" />
<property name="base" value="${ldap.base}" />
<property name="userDn" value="${ldap.user}" />
<property name="password" value="${ldap.password}" />
</bean>
<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
<constructor-arg ref="ldapContextSource" />
</bean>
Can I move just this part to be a Java config ? Or would the references be an issue.
Thank You
You can move it to Java Config
Declare configuration class
#Configuration
public class AppConfig {
#Bean
public LdapContextSource ldapContextSource(){
LdapContextSource lcontext = new LdapContextSource();
lcontext.setUrl("${ldap.url}");
lcontext.setBase("${ldap.base}");
lcontext.setUserDn("${ldap.user}");
lcontext.setPassword("${ldap.password}");
return lcontext;
}
#Bean
public LdapTemplate LdapTemplate(){
LdapTemplate lTemplate = new LdapTemplate(ldapContextSource());
return lTemplate;
}
}
In your XML add
<context:annotation-config/>
<bean class="com.mypackage.AppConfig"/>

In an old spring application, I have the following in the applicationContext.xml file, now I need to rewrite it in Spring Boot?
How do I do that in Spring Boot?
Any help or hint would be greatly appreciated it?
Spring applicationContext.xml
<bean id="dealTicketDAO" class="SqlMapDealTicketDAO">
<property name="dealTicketMapper" ref="dealTicketMapper" />
</bean>
<bean id="dealTicketMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="DealTicketMapper"/>
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>
<bean id="dealTicketService" parent="baseTransactionProxy">
<property name="target">
<bean class="DealTicketServiceImpl">
<property name="dealTicketDAO">
<ref local="dealTicketDAO"/>
</property>
</bean>
</property>
</bean>
Create a class annotated with #Configuration
the dependency is (org.springframework.context.annotation.Configuration)
and for each bean declaration in your XML file create a #Bean (org.springframework.context.annotation.Bean) method within this class.
#Configuration
public class MyConfiguration {
#Bean
public MapperFactoryBean<DealTicketMapper> dealTicketMapper() throws Exception {
MapperFactoryBean<DealTicketMapper> factoryBean = new MapperFactoryBean<>(DealTicketMapper.class);
factoryBean.setSqlSessionFactory(sqlSessionFactory());
return factoryBean;
}
#Bean
public DealTicketService dealTicketService(DealTicketDAO dealTicketDAO){
return new DealTicketServiceImpl(dealTicketDAO);
}
this should surely help you
Posted my current configuration
#Configuration
public class Config {
#Value("${spring.datasource.primary.jndi-name}")
private String primaryJndiName;
#Value("${spring.datasource.secondary.jndi-name}")
private String secondaryJndiName;
#Primary
#Bean(destroyMethod = "") // destroy method is disabled for Weblogic update app ability
public DataSource primaryDs() {
JndiDataSourceLookup lookup = new JndiDataSourceLookup();
return lookup.getDataSource(primaryJndiName);
}
#Bean(destroyMethod = "") // destroy method is disabled for Weblogic update app ability
public DataSource secondaryDs() {
JndiDataSourceLookup lookup = new JndiDataSourceLookup();
return lookup.getDataSource(secondaryJndiName);
}
}
I implemented this way and it is working
you can put your jndi values in one properties file and then load that property file in your bean defination.xml
jndi.properties
#JNDI property for job repository
job.repository.db.connection=jdbc/pgDB
#JNDI property for application
application.db.connection=jdbc/db2Conn
Bean-defination.xml
<bean id="propertyPlaceholderConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath*:/properties/jndi.properties</value>
</list>
</property>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
</bean>
<bean id="jobRepoDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="${job.repository.db.connection}" />
</bean>
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="${application.db.connection}" />
</bean>
My config:
<bean parent="cache-template">
<property name="name" value="yagoLabel" />
<property name="cacheMode" value="PARTITIONED" />
<property name="atomicityMode" value="TRANSACTIONAL" />
<property name="distributionMode" value="PARTITIONED_ONLY" />
<property name="backups" value="1" />
<property name="store">
<bean class="id.ac.itb.ee.lskk.lumen.yago.YagoLabelCacheStore" autowire="byType" init-method="init" />
</property>
<property name="writeBehindEnabled" value="true" />
<property name="writeBehindFlushSize" value="102380" />
<property name="writeBehindFlushFrequency" value="30000" />
<property name="writeBehindBatchSize" value="10240" />
<property name="swapEnabled" value="false" />
<property name="evictionPolicy">
<bean class="org.gridgain.grid.cache.eviction.lru.GridCacheLruEvictionPolicy">
<property name="maxSize" value="102400" />
</bean>
</property>
</bean>
And I start GridGain as follows:
My GridCacheStore implementation:
public class YagoLabelCacheStore extends GridCacheStoreAdapter<String, YagoLabel> {
private static final Logger log = LoggerFactory
.getLogger(YagoLabelCacheStore.class);
private DBCollection labelColl;
#GridSpringResource(resourceName="mongoDb")
private DB db;
#Inject
private GridGainSpring grid;
#PostConstruct
public void init() {
log.info("Grid is {}", grid);
labelColl = db.getCollection("label");
}
I start GridGain as follows:
String entityId = "Muhammad";
try (AnnotationConfigApplicationContext appCtx
= new AnnotationConfigApplicationContext(LumenConfig.class)) {
Grid grid = appCtx.getBean(Grid.class);
GridCache<String, YagoLabel> labelCache = YagoLabel.cache(grid);
log.info("Label for {}: {}", entityId, labelCache.get(entityId));
}
LumenConfig Spring configuration contains a DB bean named mongoDb.
However this throws NullPointerException because db is not injected properly. I tried #Inject GridGainSpring just for testing, and even GridGainSpring itself is not injected.
I also tried setting <property name="db" ref="mongoDb"/> in the GridGain Config XML but Spring complains cannot find the bean.
My workaround is to put it inside a public static field but that's soo hacky: https://github.com/ceefour/lumen-kb/blob/b8445fbebd227fb7ac337c758a60badb7ecd3095/cli/src/main/java/id/ac/itb/ee/lskk/lumen/yago/YagoLabelCacheStore.java
The way is to load the GridConfiguration using Spring, then pass it to GridGainSpring.start() :
// "classpath:" is required, otherwise it won't be found in a WAR
#ImportResource("classpath:id/ac/itb/ee/lskk/lumen/core/lumen.gridgain.xml")
#Configuration
public static class GridGainConfig {
#Inject
private ApplicationContext appCtx;
#Inject
private GridConfiguration gridCfg;
#Bean(destroyMethod="close")
public Grid grid() throws GridException {
return GridGainSpring.start(gridCfg, appCtx);
}
}

I am using <mvc:annotation-driven/> and I would like to configure RequestMappingHandlerMapping for disabling useTrailingSlashMatch. When I declare another RequestMappingHandlerMapping, I will end up 2 RequestMappingHandlerMapping. How can I configure RequestMappingHandlerMapping ?
As you have already noted, this is feasible in xml by removing mvc:annotation-driven and replacing with the entire xml equivalent:
<bean name="handlerAdapter" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="webBindingInitializer">
<bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
<property name="conversionService" ref="conversionService"></property>
<property name="validator">
<bean class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>
</property>
</bean>
</property>
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>
<bean class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"/>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
<bean class="org.springframework.http.converter.StringHttpMessageConverter"></bean>
<bean class="org.springframework.http.converter.ResourceHttpMessageConverter"></bean>
<bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"></bean>
<bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter"></bean>
</list>
</property>
</bean>
<bean name="handlerMapping" class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
<property name="useTrailingSlashMatch" value="true"></property>
</bean>
Can you try with Java config to override RequestMappingHandlerMapping value
#Configuration
#ComponentScan(basePackages = "base.package.name")
public class WebAppConfig extends WebMvcConfigurationSupport {
#Override
#Bean
public RequestMappingHandlerMapping requestMappingHandlerMapping() {
RequestMappingHandlerMapping rmh = super.requestMappingHandlerMapping();
rmh.setUseTrailingSlashMatch(false);
return rmh;
}
}
If you want a solution that doesn't involve duplicating functionality in Spring then you can override the DisplatcherServlet. in Servlet 3.0 container this might look like:
#WebServlet(name="spring-dispatcher", loadOnStartup=1, urlPatterns={"/"},
initParams={
#WebInitParam(name="contextConfigLocation",
value="/WEB-INF/spring/spring-dispatcher-servlet.xml")})
public class MyDispatcherServlet extends DispatcherServlet {
#Override
protected void initStrategies(ApplicationContext context) {
super.initStrategies(context);
for (RequestMappingInfoHandlerMapping handlerMapping
: BeanFactoryUtils.beansOfTypeIncludingAncestors(
context, RequestMappingInfoHandlerMapping.class, true, false).values()) {
handlerMapping.setUseTrailingSlashMatch(false);
}
}
}
Add the following to your spring configuration file to toggle the useTrailingSlashMatch field.
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
<property name="useTrailingSlashMatch" value="true">
</property>
</bean>
I'm brand spanking new at Spring and have gotten a majority of the knowledge I do have from the Spring Recipes book from Apress.
I've got LDAP authentication working with Spring Security within one webapp. I would like to rip out my application context beans and properties files from this one webapp, however, and somehow externalize them so that all of our webapps can reference the same beans. So when we need to change something (like the ldapuser or the ldap urls), we change it in one place and the rest of the apps just know.
UPDATE
I've implemented Reloadable Spring Properties which is reloading properties when the files they come from are touched. I am using encrypted properties, however, so below is class I created on top of the Reloadable Spring Properties ones.
ReloadingEncryptablePropertyPlaceholderConfigurer.java
package;
import java.util.Properties;
import java.util.Set;
import org.apache.commons.lang.Validate;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.jasypt.encryption.StringEncryptor;
import org.jasypt.util.text.TextEncryptor;
import org.jasypt.properties.PropertyValueEncryptionUtils;
import org.springframework.beans.factory.BeanDefinitionStoreException;
public class ReloadingEncryptablePropertyPlaceholderConfigurer extends ReloadingPropertyPlaceholderConfigurer {
protected final Log logger = LogFactory.getLog(getClass());
private final StringEncryptor stringEncryptor;
private final TextEncryptor textEncryptor;
public ReloadingEncryptablePropertyPlaceholderConfigurer(TextEncryptor textEncryptor) {
super();
logger.info("Creating configurer with TextEncryptor");
Validate.notNull(textEncryptor, "Encryptor cannot be null");
this.stringEncryptor = null;
this.textEncryptor = textEncryptor;
}
public ReloadingEncryptablePropertyPlaceholderConfigurer(StringEncryptor stringEncryptor) {
super();
logger.info("Creating configurer with StringEncryptor");
Validate.notNull(stringEncryptor, "Encryptor cannot be null");
this.stringEncryptor = stringEncryptor;
this.textEncryptor = null;
}
#Override
protected String convertPropertyValue(String originalValue) {
if (!PropertyValueEncryptionUtils.isEncryptedValue(originalValue)) {
return originalValue;
}
if (this.stringEncryptor != null) {
return PropertyValueEncryptionUtils.decrypt(originalValue, this.stringEncryptor);
}
return PropertyValueEncryptionUtils.decrypt(originalValue, this.textEncryptor);
}
#Override
protected String parseStringValue(String strVal, Properties props, Set visitedPlaceholders) throws BeanDefinitionStoreException {
return convertPropertyValue(super.parseStringValue(strVal, props, visitedPlaceholders));
}
}
And here's how I use it in my securityContext.xml:
<bean id="securityContextSource" class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
<constructor-arg value="ldaps://ldapserver" />
<property name="urls" value="#{ldap.urls}" />
</bean>
<bean id="timer" class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<bean id="reloadProperties" class="org.springframework.scheduling.timer.ScheduledTimerTask">
<property name="period" value="1000"/>
<property name="runnable">
<bean class="ReloadConfiguration">
<property name="reconfigurableBeans">
<list>
<ref bean="configproperties"/>
</list>
</property>
</bean>
</property>
</bean>
</property>
</bean>
<bean id="configproperties" class="ReloadablePropertiesFactoryBean">
<property name="location" value="classpath:ldap.properties"/>
</bean>
<bean id="ldapPropertyConfigurer" class="ReloadingEncryptablePropertyPlaceholderConfigurer">
<constructor-arg ref="configurationEncryptor" />
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="properties" ref="configproperties"/>
</bean>
<bean id="jasyptConfig" class="org.jasypt.encryption.pbe.config.SimpleStringPBEConfig">
<property name="algorithm" value="PBEWithMD5AndTripleDES" />
<property name="password" value="########" />
</bean>
<bean id="configurationEncryptor" class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
<property name="config" ref="jasyptConfig" />
</bean>
How about:
Writing a method that returns a list
of LDAP servers - reading from a
database table or property files
expose this wethod via jndi and use it to inject a list of the servers into your spring config
If you need the ldap servers to be refreshed dynamically you could have a job poll for changes periodically or else have an admin webpage or jmx bean to trigger the update. Be careful of concurrency isses for both these methods (something reading the list while you are updating)
Wouldn't that be Spring Security? It can deal with LDAPs. And if you make it one security service that everyone uses, wouldn't that be the way to manage it?
