spring boot 入門

首先第一步創建一個maven工程

springboot1

1.在pom文件裏添加下面配置，依賴。

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>spring.boot.test</groupId>
    <artifactId>spring-boot-web-test</artifactId>
    <version>1.0-SNAPSHOT</version>
    <!-- 繼承基本的父級  -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.2.5.RELEASE</version>
    </parent>

    <!-- 添加web依賴 -->
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

    <!-- Package as an executable JAR -->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>





</project>

2.編寫一個Javabean.

public class User {

    private Long id;
    private String name;
    private int age;

3.controller

package com.controller;

/**
 * Created by zhangtao4 on 2015/9/9.
 */


import com.entity.User;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@EnableAutoConfiguration
@RestController
@RequestMapping("/user")
public class UserController {

    @RequestMapping("/{userId}")
    public User view(@PathVariable("userId") Long userId) {
        User user = new User();
        user.setId(userId);
        user.setAge(18);
        user.setName("hello world");
        return user;
    }

    public static void main(String[] args) {
        SpringApplication.run(UserController.class);
    }

}
