新建maven项目
添加依赖
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.2.RELEASE</version>

一个User类
public class User { private String name;
private int age;
private String address; public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
} public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
一个Controller
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController; @RestController
@RequestMapping("/")
public class UserController { @RequestMapping("/testJson")
public User testJson() {
User user = new User();
user.setName("lijia");
user.setAge(27);
user.setAddress("北京");
return user;
} }
一个启动类
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication
public class ApplicationApp { public static void main(String[] args) { SpringApplication.run(ApplicationApp.class, args);
}
}
启动,然后输入http://localhost:8080/testJson
是不是很简单
