springboot 访问的方式支持类似于restful风格的访问
本文采用的jdk版本为1.7 spring boot 版本为1.4.7.RELEASE
首先看下 maven的配置文件

maven 创建的项目 分为 文件资源存放路径 src/main/resource/ 我们需要创建 src/main/java 将我们的代码放入这个 source folder中,具体的类如下，此处简单示例 只有两个类启动数据的类
package com.julongtech.action;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* 启动类
* @author julong
* @date 2017-8-22 下午2:28:52
*/
@SpringBootApplication
public class SpringBootStart {
/**
* @param args
* @author julong
* @date 2017-8-21 下午2:25:14
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
SpringApplication.run(SpringBootStart.class, args);
}
}
第二个类为业务操作类
package com.julongtech.action;
import java.util.HashMap;
import java.util.Map;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.julongtech.entity.UserInfo;
/**
* 数据处理类
* @author julong
* @date 2017-8-22 下午2:28:32
*/
@RestController
public class Example {
/**
* 返回字符串
* @return
* @author julong
* @date 2017-8-22 下午3:01:03
*/
@RequestMapping(value="/",method=RequestMethod.GET)
public String home() {
return "Hello World!";
}
/**
* 返回一个对象
* @return
* @author julong
* @date 2017-8-22 下午3:01:20
*/
@RequestMapping(value="/index",method=RequestMethod.GET)
public UserInfo index() {
UserInfo user = new UserInfo();
user.setUserName("张三");
return user;
}
/**
* 返回一个map对象
* @return
* @author julong
* @date 2017-8-22 下午3:01:38
*/
@RequestMapping(value="/hello",method=RequestMethod.GET)
public Map<String, Object> hello() {
Map<String, Object> maps = new HashMap<String, Object>();
maps.put("1", "test");
maps.put("2", "test");
maps.put("3", "test");
maps.put("4", "test");
maps.put("5", "test");
return maps;
}
}
启动程序：
