2.RestMain.java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * 测试RestFul
 *
 */
@SpringBootApplication //等同于 @Configuration @EnableAutoConfiguration @ComponentScan
public class RestMain 
{
    public static void main( String[] args )
    {
        SpringApplication.run(RestMain.class, args);  
    }   
}

3.BeanConfig.java

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;

@Configuration
@ComponentScan(basePackages="com.maven") //这是扫描的包的主路径
@EnableAspectJAutoProxy   //AOP代理自动配置
public class BeanConfig {
//    @Bean
//    public AppService service(){
//        return new AppService();
//    }
    
//    @Bean
//    public User user(){
//        return new User();
//    }
    
//    @Bean
//    public ContactBook contactBook(){
//        return new ContactBook();
//    }
    
//    @Bean
//    public AspectConcern aspectConcern(){
//        return new AspectConcern();
//    }
}

4.WebConfig.java

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter{
    /**
     * 这里的@bean()需要赋值一个名称，否则会抛出没有创建这个bean的异常
     * 
     */
    @Bean("defaultServletHandlerMapping")
    public ViewResolver viewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("WEB-INF/views/");
        resolver.setSuffix(".jsp");
        resolver.setExposeContextBeansAsAttributes(true);
        return resolver;
    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }
    
}

5.LoginController.java

        //请求重定向
        response.sendRedirect("http://www.baidu.com");
        return "<div>Hello</div>";
    }    
    
    /**
     * @param user      从体中获取的json数据(体中的数据与User里面的属性一一对应)
     * @param pathValue 从url地址中获取的路径名称
     * @param name      从url地址中获取的对应的参数的值(defaultValue表示默认值)
     * @param id
     * @return

    @RequestMapping(value="/login/{pathValue}",method=RequestMethod.POST)
    @ResponseBody
    public User posting(@RequestBody User user,@PathVariable String pathValue,@RequestParam(defaultValue="tianheng")String name,int id){        
        return user;
    }
}
