Spring mvc config using annotation:

package com.vito16.activiti.demo1.config;

import com.alibaba.druid.pool.DruidDataSourceFactory;

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
    @Bean
    public InternalResourceViewResolver internalResourceViewResolver() {
        InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver();
        internalResourceViewResolver.setPrefix("/WEB-INF/views/");
        internalResourceViewResolver.setSuffix(".jsp");
        return internalResourceViewResolver;
    }

    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {

    }

    @Bean
    public RequestMappingHandlerAdapter requestMappingHandlerAdapter() {
        return new RequestMappingHandlerAdapter();
    }
}  

My test controller:

package com.vito16.activiti.demo1.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 * @author Vito
 * @version 2014/6/4
 */
@Controller
public class IndexController {
    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String index() {
        return "index";
    }
}

when im visit http://127.0.0.1:8080/index result 404:

and console print message:

INFO  o.s.w.s.m.m.a.RequestMappingHandlerMapping - Mapped "{[/index],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.vito16.activiti.demo1.controller.IndexController.index()
INFO  o.s.web.servlet.DispatcherServlet - FrameworkServlet 'dispatcher': initialization completed in 265 ms
WARN  o.s.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/WEB-INF/views/index.jsp] in DispatcherServlet with name 'dispatcher'  

How to fix it? I do not have this problem before using the XML configuration over time

Answer 1

your configuration is missing

@ComponentScan(basePackages = "your package to beans")

so it cant scan your beans like controller or whatever you try to make as bean

so add this on top of your configuration class like below

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.vito16.activiti.demo1")
public class WebConfig extends WebMvcConfigurerAdapter {
    @Bean
    public InternalResourceViewResolver internalResourceViewResolver() {
        InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver();
        internalResourceViewResolver.setPrefix("/WEB-INF/views/");
        internalResourceViewResolver.setSuffix(".jsp");
        return internalResourceViewResolver;
    }

    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping() {
        return new RequestMappingHandlerMapping();
    }

    @Bean
    public RequestMappingHandlerAdapter requestMappingHandlerAdapter() {
        return new RequestMappingHandlerAdapter();
    }
}
