I want to send mail after processor. These is my step configuration:
public Step remindByMail() {
return stepBuilderFactory
.get("remindByMail")
.<Customer, SimpleMailMessage> chunk(1)
.reader(getCustomerList())
.processor(new MailProcessor())
.writer(new SendMail())
.build();
}
public class MailProcessor implements ItemProcessor<Customer, SimpleMailMessage> {
private String from = "aaa#oku.com";
#Override
public SimpleMailMessage process(Customer customer) throws Exception {
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(from);
message.setTo("duyetpt#oku.com");
message.setSubject("Welcome " + customer.getUsername());
message.setText(customer.getInfo());
return message;
}
}
public class SendMail implements ItemWriter<SimpleMailMessage> {
#Override
public void write(List<? extends SimpleMailMessage> messages) throws Exception {
messages.stream().forEach((message)->mailSender.send(message));
}
}
And I have set these properties in application.properties file,
spring.mail.default-encoding=UTF-8
spring.mail.protocol=smtp
spring.mail.host=195.179.79.52
spring.mail.port=25
spring.mail.username=admin

What should I do to send mail using Spring Batch?
Its my guess by your error message - No authentication mechanisms supported by both server and client that below properties needs to be removed from your configuration.
spring.mail.username=admin
spring.mail.password=admin
spring.mail.properties.mail.smtp.auth=true
In Spring Boot + Batch , I send emails using my organization's server without these properties as user name & passwords are not needed because program has to reside in organization network & that is the only security.
Its altogether a different story if one is trying to use - gmail , yahoo etc.

Im new to Spring Boot and was trying to implement basic Spring Security for a single endpoint in my Spring Boot controller. But I dont know how to resolve the Circular View Error
My Controller
#Controller
#RequestMapping("/api")
public class HelloSecurityController {
#RequestMapping({"/hello"})
public static String helloWorld() {
return "hello";
}
My Security Configurer Class
#EnableWebSecurity
public class SecurityConfigurer extends WebSecurityConfigurerAdapter {
#Autowired
private MyUserDetailsService myUserDetailsService;
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(myUserDetailsService);
}
#Bean
public PasswordEncoder passwordEncoder() {
return NoOpPasswordEncoder.getInstance();
}
```
My MyUserDetailsService which returns a simple User with Password
#Service
public class MyUserDetailsService implements UserDetailsService {
#Override
public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
return new User("foo","foo", new ArrayList<>());

After logging in using the username and password at the login form page generated by spring security Im getting the error:
javax.servlet.ServletException: Circular view path [hello]: would dispatch back to the current handler URL [/api/hello] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)
I have not kept any static template (HTML/JSP) in the templates folder. I dont know if I have to as after login I just want to see a simple String. How do I resolve this?

You've almost got it, you're just missing one more configuration flag to stop that exception creeping in.
Add cloud.aws.stack.auto = false to your application.properties file thus it will not enable the automatic stack name detection for the application.
You can read up more about it in the docs: http://cloud.spring.io/spring-cloud-aws/spring-cloud-aws.html#_cloudformation_configuration_in_spring_boot
Using the response of #Chris-Turner you can add a VM option to run your app locally:
-Dcloud.aws.stack.auto=false
I'm using spring boot 2 to create a project and use websocket using reactive web dependency. My application is worked correctly until I add datarest dependency. after I add datarest dependency application give

is any way to resolve this conflict?.

spring-boot-starter-data-rest brings spring-boot-starter-web as a transitive dependency (so basically Spring MVC). This makes Spring Boot configure your application as a Spring MVC web application.
Spring Data REST does not currently support Spring WebFlux (see this issue for more information on that).
Your only choice is to remove the Spring Data REST dependency, as you can't have both Spring MVC and Spring WebFlux in the same Spring Boot application.
Just taking Spring-Boot for a spin and decided to mix in Camel because I need some arcane Headers work in the rest client I am working on. Setting up the application was fine until I added the camel-http component to my POM, then I get this on init:
Exception in thread "main" org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.
I've havent got the first idea of where to start to look for the problem. I gather Spring Boot will look up the classpath and try to wire stuff up, so is there a way for the to block the Camel packages from being acted on or something of the sort?

The exception is telling you that Spring Boot thinks you want to build a web server, but can't find the right dependencies on the classpath. The most obvious reason for that in your case would be that the HTTP dependencies you added included Servlet APIs. I see no reason why you need that for a client app, but only you would know whether you need it or not. Maybe you can exclude it?
If you do need the Servlet dependencies and just want to explicitly tell Boot that you aren't creating a web application you can set the property spring.main.web_environment=false, or use the SpringApplication (or SpringApplicationBuilder) API directly to set the same flag. See docs here for background information.
I have a Standalone Jersey server running at the beginning of my JunitTest. I'm testing if my JaxRS controller works, as well as my custom HttpClient. Please note that I've always been able to use this JaxRsResourceController embedded in glassfish.
Here is the JaxRsController (light version)
#Path("root")
public class JaxRsResourceController implements
ResourceController<HttpServletRequest> {
#Context
private UriInfo context;
#Context
HttpServletRequest request;
#Context
HttpServletResponse response;
#GET
public String hello(){
System.out.println("Uri is "+this.context.getBaseUri().toString());
return "Hello "+peoples;
}
}
I have no problem with the client, but when I start the server, I have :
GRAVE: The following errors and warnings have been detected with resource and/or provider classes:
SEVERE: Missing dependency for field: javax.servlet.http.HttpServletRequest com.robustaweb.library.rest.controller.implementation.JaxRsResourceController.request
SEVERE: Missing dependency for field: javax.servlet.http.HttpServletResponse com.robustaweb.library.rest.controller.implementation.JaxRsResourceController.response
at com.sun.jersey.api.container.httpserver.HttpServerFactory.create(HttpServerFactory.java:172)
at com.robustaweb.library.rest.server.JerseyServer.startServer(JerseyServer.java:44)
Basically it says that at the #Context injection time, there is no dependency on the HttpServletRequest.
However if I remove the #Context annotations on request and response, but keep it for UriInfo context, it's ok, and I can read the Uri.
I changed a few times the Maven pom wich is now to force the libs in:
<dependencies>
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-server</artifactId>
<version>1.14</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
</dependency>
</dependencies>
Any idea ?
servlet dependencies were separated to another module, try adding
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-servlet</artifactId>
<version>1.14</version>
</dependency>
to your pom.
It was not easy, but I found out. The thing is that in my JUnit test, I was creating the server like this :
HttpServer server = HttpServerFactory.create(url);
But that way, you create a lightweight container that does not have servlet containers, and so is the failure reason. So in order to have it all, I used the jersey-test-framework that allow to use the Grizzly web container (or even Embedded glassfish).
Here is the maven :
<dependencies>
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
<version>1.1.1</version>
</dependency>
<!-- Unit test are using jersey server directly -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.8.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>com.sun.jersey.test.framework</groupId>
<artifactId>jersey-test-framework</artifactId>
<version>1.0.3</version>
<scope>test</scope>
</dependency>
</dependencies>
Here is the JerseyServerTest : note that it extends JerseyTest
public class JerseyServerTest extends JerseyTest {
protected String baseUri = "http://localhost:" + TestConstants.JERSEY_HTTP_PORT + "/";
public JerseyServerTest() throws Exception {
super("com.robustaweb.library.rest.controller");
/*
It's possible to NOT call the super() but to manually do :
1) ApplicationDescriptor appDescriptor = new ApplicationDescriptor()
.setRootResourcePackageName(resourcePackageName) // resource packages
.setContextPath(contextPath) //context of app
.setServletPath(servletPath); // context of spi servlet
2)setupTestEnvironment(appDescriptor);
*/
}
#Test
public void testHelloWorldRequest() {
SunRestClient client = new SunRestClient(baseUri + "root");
String result = client.GET("", null);
System.out.println(result);
}
#Test
public void testDeleteRequest() {
SunRestClient client = new SunRestClient(baseUri + "root");
String result = client.DELETE("john", null);
System.out.println(result);
}
}
And finally the Resource file, that contains #GET and #DELETE
#Path("root")
public class JaxRsController extends JaxRsResourceController{
List<String> peoples = new ArrayList<String>();
#GET
public String hello(){
System.out.println("Uri is "+getUri());
return "Hello "+peoples;
}
#DELETE
#Path("{name}")
public String deletePeople(#PathParam("name") String name){
System.out.println("deleting "+name);
this.peoples.remove(name);
return String.valueOf(peoples.size());
}
}
And now it works !
I had some help in this article, and there is a small chapter on the documentation. Beeing able to attach the source code of the Jersey framework really helped, so thantks to IntelliJ also.
