This is my RedisHttpSessionConfig.java class where I wrote code for RedisData
import org.springframework.context.annotation.Bean;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
#EnableRedisHttpSession
public class RedisHttpSessionConfig {
#Bean
public LettuceConnectionFactory connectionFactory() {
return new LettuceConnectionFactory();
}
}
here is my SecurityConfig.java class
package com.xyz.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import com.netelixir.service.UserSecurityService;
import org.springframework.session.web.http.HeaderHttpSessionIdResolver;
import org.springframework.session.web.http.HttpSessionIdResolver;
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private Environment env;
#Autowired
private UserSecurityService userSecurityService;
private BCryptPasswordEncoder passwordEncoder() {
return SecurityUtility.passwordEncoder();
}
private static final String[] PUBLIC_MATCHERS = {
"/css/**",
"/js/**",
"/user/**"
};
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable().cors().disable().httpBasic().and().authorizeRequests()
.antMatchers(PUBLIC_MATCHERS).permitAll().anyRequest().authenticated();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userSecurityService).passwordEncoder(passwordEncoder());
}
#Bean
public HttpSessionIdResolver httpSessionIdResolver() {
return HeaderHttpSessionIdResolver.xAuthToken();
}
}
Adding io.lettuce:lettuce-core as a dependency should fix the exception.
I'm new to Spring MVC. I know there are a lot of similar questions like this but I already tried most of them for several hours and still facing the issue that 404 error shows up when I request http://localhost:8080/SpringRESTFulExample/ from browser. But there's no any exception in console.
Here is my code,
RootConfig.java
#Configuration
#ComponentScan(basePackages = "springrestful_example")
public class RootConfig {
}
WebConfig.java
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = "springrestful_example")
public class WebConfig extends WebMvcConfigurerAdapter{
#Bean
public InternalResourceViewResolver resolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setViewClass(JstlView.class);
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}
.
.
.
}
WebInitializer.java
public class WebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {RootConfig.class};
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] {WebConfig.class};
}
#Override
protected String[] getServletMappings() {
return new String[] {"/"};
}
}
UserController.java
#RestController
public class UserController {
#RequestMapping(value = "/", method = RequestMethod.GET)
public ModelAndView index(){
ModelAndView modelandView = new ModelAndView("index");
return modelandView;
}
.
.
}
index.jsp is under /WEB-INF/views/index.jsp

That's all I got. Correct me if my code is being wrong. I will be happy if i see Hello World text written in index.jsp body.
What package are your Config classes in? Are they in basePackages you specify? Try not specifying the basePackages in the Component scan annotation.

Then when I am trying to get java objects (in client application) via org.springframework.web.client.RestTemplate I have following exception:
Exception in thread "main"
org.springframework.http.converter.HttpMessageNotReadableException:
Could not read [class com.example.web.Contacts]; nested exception is
org.springframework.oxm.UnmarshallingFailureException: SAX reader
exception; nested exception is org.xml.sax.SAXException: The class for
the root element 'Contacts' could not be found. at
org.springframework.http.converter.xml.MarshallingHttpMessageConverter.re
adFromSource(MarshallingHttpMessageConverter.java:134)
...
I belive that something wrong is with my mapping file. As You can see I have triple contacts tag even in mapping file I have other names.. Do anyone know what can be a reason of having this exception/wrong xml format?
What is happening is that when unmarshaller is looking for class he's looking for alias "Contacts" as in XML. What he has in cache is "contacts" mapping and its not the same as "Contacts". Problem was that marshaller library was not the same as unmarshaller. Probably something wrong in configuration..
What I did is change of implementation to jaxb I put #XMLRootElement and #XMLElement on model classes and completely removed configuration of messageConverters in mvc:annotation-driven (also mapping xml files). On client application I changed messageConverter to:
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
<property name="messageConverters">
<list>
<bean
class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
<property name="marshaller" ref="jaxb2Marshaller" />
<property name="unmarshaller" ref="jaxb2Marshaller" />
</bean>
</list>
</property>
</bean>
<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="classesToBeBound">
<list>
<value>com.example.web.model.Contact</value>
<value>com.example.web.Contacts</value>
</list>
</property>
</bean>
And everything works fine.
First note that I am a total beginner regarding this. I started spring maven web project and wrote 3 classes (posted below).
I put the project to be run on my tomcat server (from eclipse) and when I start it i can access localhost:8080 (tomcat default page is shown), but when i try to access localhost:8080/greeting i get 404 error, what am I doing wrong? I'll also post my pom.xml
Thank you
Greeting:
package hello;
public class Greeting {

public Greeting(long id, String content) {
this.id = id;
this.content = content;

}
}

If you deploy your application into a standalone Tomcat instance and it is not deployed as the ROOT application, you have to add the name of the application in your URL. You can check the Tomcat log for the exact name. If you named your project "helloworld", then Eclipse usually deploys the project with that name as application name, so you should call your application with the URL http://localhost:8080/helloworld/greeting
Unless you really need to deploy your application to an external Tomcat server, you can solve your problem by just running your application's main method directly. Spring Boot will start an embedded Tomcat instance for you.
If you need to be able to deploy your application to an external Tomcat server, then you need to change your Application class a little bit so that it'll start up correctly. You need to extend SpringBootServletInitializer and override the configure method:
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
This is covered in the traditional deployment section of the Spring Boot reference documentation.
