有段时间没有写博客，最近入职，准备静下心来好好学习技术，把以前没用的博客删掉，从头开始写博客。本文是介绍springboot如何与springmvc完成合作，而且也只是简单介绍的整合springmvc

**首先创建springboot工程，可用idea的自带的生成插件生成**

**下一步之后可选择自身所需的依赖**

**接下来我们创建一个controller**

package com.example.springboot01.controller;
    
    import com.example.springboot01.entity.User;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * Created by linjiaming
     */
    @RestController
    public class HelloWorld {
    	//读取配置文件中数值
        @Value("${boot.name}")
        private String name;
    
        @RequestMapping("hello")
        public User hello(){
            User user = new User();
            user.setName(name);
            user.setAge("18");
            return user;
        }
    }

定义一个实体类，作为返回前台的json数据

package com.example.springboot01.entity;
    
    /**
     * Created by linjiaming
     */
    public class User {
        private String name;
        private String age;
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public String getAge() {
            return age;
        }
    
        public void setAge(String age) {
            this.age = age;
        }
    
        @Override
        public String toString() {
            return "User{" +
                    "name='" + name + '\'' +
                    ", age='" + age + '\'' +
                    '}';
        }
    }

**运行项目输入地址访问**
