ZK with Spring Session jdbc throws: Unable to serialize entry - spring
We have an aplication based on ZK with Spring Boot / Spring Security / JPA implementation running in Google Cloud Run, within a docker. It works quite fine with non jdbc persistent sessions. Google is probably sending the requests with the same JSESSION_ID to same server of the server pool.
Unfortunatelly, too often the aplication closes and the user has to relogin, probably when the server previously answering the requests is shutdown or becomes too busy and Google decides to change the destination server.
Our idea to improve usability was to implement the Spring persistent session which is very easy to implement. It is just about adding in the Pom :
<dependency>
<groupId>org.springframework.session</groupId>
<artifactId>spring-session-jdbc</artifactId>
</dependency>
and the .properties :
spring.session.store-type=jdbc
spring.session.jdbc.initialize-schema=ALWAYS
The table for holding the session data is created, the server starts, but when trying to load the login page we get the following error :

This error looks like this is one of the ZK framework object that is not serializable, I double checked that all the session data is serializable and did not find any thing wrong on that side.
I can add here some config files in this post, but i basically followed the instruccions from :
https://www.zkoss.org/wiki/ZK_Installation_Guide/Setting_up_Servers/Google_App_Engine
Any help to succeed implementing the Spring Session store with ZK is welcome !
This is a "org.zkoss.bind.BindComposer" Object that fails to serialize any idea why ?
as per very good Hawk idea, here is the log with the detailed error log :

Please call System.setProperty("sun.io.serialization.extendedDebugInfo", "true"); which will print details debugging information about which member field is not serializable.
updated:
If you check the exception, the last field it printed is the root cause of NotSerializableException:
- field (class "org.springframework.aop.support.AbstractGenericPointcutAdvisor", name: "advice", type: "interface org.aopalliance.aop.Advice")
You can trace the object path from the root object to know how your ViewModel references AbstractGenericPointcutAdvisor.
- root object (class "org.zkoss.zk.ui.http.SerializableSession", org.zkoss.zk.ui.http.SerializableSession#7f4fb979)
Hence, I think the exception is not caused by ZK.

Spring Cloud Stream - failed to deserialize - failed to resolve class name. Class not found
Application A writes to a Kafka Topic below User object (json):
public class UserEvent {
private UUID id;
private Object payload; // contains User fields name etc.
}
Application B is trying to consume this User object (User.java resides in application B project) with below application.yml (multiple binders):
binders:
azureEventHub:
type: kafka
environment:
spring:
kafka:
bootstrap-servers: servicebus.windows.net:9093
consumer:
key-deserializer: org.springframework.kafka.support.serializer.ErrorHandlingDeserializer
value-deserializer: org.springframework.kafka.support.serializer.ErrorHandlingDeserializer
properties:
spring.deserializer.key.delegate.class: org.apache.kafka.common.serialization.StringDeserializer
spring.deserializer.value.delegate.class: org.springframework.kafka.support.serializer.JsonDeserializer
spring.json.trusted.packages: com.*
spring.json.value.default.type: com.applicationb.User
Below is how my Spring Cloud Stream Processor class looks:
#Bean
public Function<Message<User>, String> userProcessor()
{.. }
But instead of converting the Message payload to "User" class it keeps throwing the error with the
Parent class "UserEvent" not found.
org.springframework.kafka.listener.ListenerExecutionFailedException:
Listener failed; nested exception is org.springframework.kafka.support.serializer.DeserializationException:
failed to deserialize; nested exception is org.springframework.messaging.converter.MessageConversionException:
failed to resolve class name. Class not found [com.abcd.UserEvent];
nested exception is java.lang.ClassNotFoundException: com.abcd.UserEvent
Any ideas ?
The deserializer will use type information in the headers before falling back to the default (User). Also set spring.json.use.type.headers to false.
why jdk proxy could not be injected
I use Aspect like this:
#Aspect
#Component
public class DataSourceAspect {
#Pointcut("#target(com.chen.dynamicsource.aspect.DataSource)")
public void pointCut() {
}
#Before("pointCut()")
public void doBefore(JoinPoint joinPoint) {}
}
And I add it to application.yml:
spring
aop:
proxy-target-class: false
When I run the application. I get the following error:
***************************
APPLICATION FAILED TO START
***************************
Description:
The bean 'dispatcherServlet' could not be injected because it is a JDK dynamic proxy
The bean is of type 'com.sun.proxy.$Proxy67' and implements:
org.springframework.context.ApplicationContextAware
org.springframework.core.env.EnvironmentCapable
org.springframework.context.EnvironmentAware
javax.servlet.Servlet
javax.servlet.ServletConfig
java.io.Serializable
org.springframework.aop.SpringProxy
org.springframework.aop.framework.Advised
org.springframework.core.DecoratingProxy
Expected a bean of type 'org.springframework.web.servlet.DispatcherServlet' which implements:
I know I can use statically evaluated pointcut designators like within () and change the value of proxy-target-class to true to avoid the problem.
But I just want to know why jdk proxy could not be injected.
MybatisAutoConfiguration didn't create dataSource bean
I have a SpringBoot 2.0.4.RELEASE project,using mybatis-spring-boot-autoconfigure-1.3.2.jar,and it works fine. mybatis-spring-boot-autoconfigure-1.3.2.jar will create the bean datasource of type [com.zaxxer.hikari.HikariDataSource]. But when I use jar xvf to extract the jar file,then I use jar cvmf0 /META-INF/MANIFEST.MF to recover the jar.Although the jar is the same,but it can't create the datasource bean. I use java -Ddebug -jar to run my project,find out the spring-boot-2.0.4.RELEASE.jar is not on the top of classpath. Here is some error log: MybatisAutoConfiguration: Did not match: - #ConditionalOnBean (types: javax.sql.DataSource; SearchStrategy: all) **did not find any beans of typejavax.sql.DataSource** (OnBeanCondition) Matched: - #ConditionalOnClass found required classes 'org.apache.ibatis.session.SqlSessionFactory','org.mybatis.spring.SqlSessionFactoryBean'; #ConditionalOnMissingClass did not find unwanted class (OnClassCondition) Caused by: java.lang.IllegalArgumentException: Property'sqlSessionFactory' or 'sqlSessionTemplate' are required at org.springframework.util.Assert.notNull(Assert.java:193) ~[spring-core-5.0.8.RELEASE.jar!/:5.0.8.RELEASE] at org.mybatis.spring.support.SqlSessionDaoSupport.checkDaoConfig(SqlSessionDaoSupport.java:74)~[mybatis-spring-1.3.2.jar!/:1.3.2] at org.mybatis.spring.mapper.MapperFactoryBean.checkDaoConfig(MapperFactoryBean.java:73) ~[mybatis-spring-1.3.2.jar!/:1.3.2] at org.springframework.dao.support.DaoSupport.afterPropertiesSet(DaoSupport.java:44~[spring-tx-5.0.8.RELEASE.jar!/:5.0.8.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1758)~[spring-beans-5.0.8.RELEASE.jar!/:5.0.8.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1695)~[spring-beans-5.0.8.RELEASE.jar!/:5.0.8.RELEASE] ... 108 common frames omitted The application.yml is: spring: profiles: active: prod datasource: name: dataSource url: xxx username: xxx password: xxx #type: com.alibaba.druid.pool.DruidDataSource driver-class-name: XXXX mybatis: typeAliasesPackage: xxx mapperLocations: classpath:mybatis/mapper/*Mapper.xml
Grails: Error creating bean with name 'properties': Bean definition is abstract
I'm new to Grails so I posted a question a few days ago on how to do a query to a different Datasource: Grails - Getting data from a different datasource and saving it in my Grails database The answer above worked, but then I got a strange error when I tried to view or modify anything in my default datasource. In this case I tried to go to index view of my Client controller which uses some basic scaffolding: [http-bio-8080-exec-10] ERROR spring.ReloadAwareAutowireCapableBeanFactory - Bean couldn't be autowired using grails optimization: Error creating bean with name 'properties': Bean definition is abstract [http-bio-8080-exec-10] ERROR spring.ReloadAwareAutowireCapableBeanFactory - Retrying using spring autowire [http-bio-8080-exec-10] ERROR errors.GrailsExceptionResolver - BeanIsAbstractException occurred when processing request: [GET] /EmmaRestServer/client/index Error creating bean with name 'properties': Bean definition is abstract. Stacktrace follows: Message: Error creating bean with name 'properties': Bean definition is abstract If I remove the second datasource, this problem disappears. What could be causing this issue?
I had some extra configurations in the resources.groovy. I removed them and now it looks like this, and it works properly:
beans = {
dataSource_drupal(DataSource) { bean ->
bean.destroyMethod = 'close'
driverClassName = "com.mysql.jdbc.Driver"
username = "user"
password = "password"
url = "jdbc:databaseURL
}
}
spring aop - exception while creating advice around JdbcTemplate methods
I've a web application that uses apache dbcp and spring jdbc to perform database operations on an oracle database. I need to write a performance logger that logs the individual times of each database operation. I tried writing an around advice on all 'execute' methods of org.springframework.jdbc.core.JdbcTemplate but it results in an error when spring gets initialized. The logger class and the exception stacktrace is as follows:-
I also tried to use CGLIB proxies by enabling but it errors out on dao classes that extends from spring's StoredProcedure class and use constructor injection.
#Aspect
public class Logger {
#Around("this(org.springframework.jdbc.core.JdbcTemplate) && execution(* execute(*))")
public Object invoke(ProceedingJoinPoint pjp) throws Throwable {
long time = System.currentTimeMillis();
Object result = pjp.proceed();
LOGGER.debug("time consumed = " + (System.currentTimeMillis() - time));
return result;
}
