spring boot 是spring 4.0提供的微框架，支持 jdk 1.8, maven 3以上, 否則會(huì)報(bào)一些錯(cuò)誤。

2. 然后就是提供的接口類UserController， 實(shí)體類User， 主要是幾個(gè)注解@RestController l類同spring mvc 的@Controller@RequestMapping 類同spring mvcpackage two;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/user")
public class UserController {
@RequestMapping("/hello")
public User view(){
User user=new User();
user.setId((long)100);
user.setName("fanjs");
return user;
}
package two;
public class User {
private Long id;
private String name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
3. 然后就是程序啟動(dòng)，這里不需要spring xml文件，完全依賴注解。@EnableAutoConfiguration
@Configuration
@ComponentScan
package two;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class RunMain {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
SpringApplication.run(RunMain.class, args);
}
}
4. 測試路徑
http://localhost:8080/user/hello
{"id":100,"name":"fanjs"}
