🍁请求映射路径

• @RequestMapping
  • 类型:方法注解类注解
  • 位置: SpringMVC控制器方法定义上方
  • 作用:设置当前控制器方法请求访问路径，如果设置在类上统一设置当前控制器方法请求访问路径前缀

@Controller
@RequestMapping("/book")
public class BookController {
    @RequestMapping("/save")
    @ResponseBody
    public String save(){
        System.out.println("Book save....");
        return "'module':'Book Save'";
    }
}

🍁案例

🔥ServletContainersInitConfig

package com.jkj.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class ServletContainersInitConfig extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[0];
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{SpringMvcConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}
/*
public class ServletContainersInitConfig extends AbstractDispatcherServletInitializer {
    //加载SpringMVC容器配置
    @Override
    protected WebApplicationContext createServletApplicationContext() {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(SpringMvcConfig.class);
        return ctx;
    }
    //设置哪些请求可以归属SpringMVC处理
    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
    //加载Spring容器配置
    @Override
    protected WebApplicationContext createRootApplicationContext() {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(SpringConfig.class);
        return ctx;
    }
}*/

🔥SpringMvcConfig

package com.jkj.config;

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

@Configuration
@ComponentScan("com.jkj.controller")
public class SpringMvcConfig {
}

🔥BookController

package com.jkj.controller;

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

@Controller
@RequestMapping("/book")
public class BookController {
    @RequestMapping("/save")
    @ResponseBody
    public String save(){
        System.out.println("Book save....");
        return "'module':'Book Save'";
    }
}

🔥UserController

package com.jkj.controller;

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

@Controller
@RequestMapping("/user")
public class UserController {
    @RequestMapping("/save")
    @ResponseBody
    public String save(){
        System.out.println("User save....");
        return "'module':'User Save'";
    }
    @RequestMapping("/del")
    @ResponseBody
    public String delete(){
        System.out.println("User delete....");
        return "'module':'User delete'";
    }
}
