SpringBoot环境搭建和返回JSON 字符串

SpringBoot并不是对Spring功能上的一种增强,而是提供了一种快速使用spring的一种方式。开箱即用,没有代码生成,也无需 XML 配置
Maven + Spring Web 项目结构在 Eclipse 下面的实现
在 POM.XML中添加,父工程依赖,springWeb工程依赖,springBoot Maven运行编译环境
<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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.itxyl.springboot</groupId> <artifactId>SpringBoot</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>SpringBoot Maven Webapp</name> <url>http://maven.apache.org</url> <!-- 必须应用springBoot 父工程依赖 --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.3.3.RELEASE</version> </parent> <!-- springWeb工程依赖 默认集成SpringMvc --> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> <!-- springBoot Maven运行编译环境 --> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin </artifactId> </plugin> </plugins> </build></project>
添加后在编写JAVA代码
package com.itxyl.controller;import java.util.ArrayList;import java.util.List;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * @RestController标注该类的所有请求方法为 返回json字符串 不做试图解析 * @author xuyalin * */@RequestMapping("/springboot")@RestControllerpublic class IndexController { @RequestMapping("/index") public String index(){ return "success"; } @RequestMapping("/index1") public String index1(){ return "success1"; } @RequestMapping("/listindex") public List<String> listIndex(){ List<String> list=new ArrayList<String>(); list.add("index"); list.add("index1"); list.add("index5"); System.out.println(list); return list; }}
package com.itxyl.service;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.context.annotation.ComponentScan;import org.springframework.stereotype.Component;import com.itxyl.controller.IndexController;/** * springBoot启动类 * @author xuyalin * */@ComponentScan(basePackages={"com.itxyl.controller"})//标示为springmvc注入类@EnableAutoConfigurationpublic class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); }}
测试就直接main方法启动,如下就启动成功了,在浏览器输入测试的话就是:http://localhost:8080/springboot/listindex。根据你自己写的路径就好了。

@EnableAutoConfiguration为springboot程序入口,一个程序就一个入口,所以可以把他单独的拿出来。
