使用Spring boot 快速创建项目

Spring boot 是整合了框架，以快速开发为目的，大大节省了开发效率。

以下是创建项目。利用STS 4.0软件使用时必须安装eclipse 和 sts 4.0 。方可打开sts4.0

创建好的项目然后建立项目结构

建立application.yml文件配置

server: port: 8888 spring: datasource: url: jdbc:sqlserver://10.10.10.2:1433;databaseName=scmis000 username: sc password: redone dbcp2: driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver initial-size: 5 min-idle: 10 max-wait-millis: 10000

系统生成的spring boot 主类

package com.xukai; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; //mapperscan扫描。这样的话就不用一个个配置了。 @MapperScan("com.xukai.mapper") @SpringBootApplication public class XmHelperApplication { public static void main(String[] args) { SpringApplication.run(XmHelperApplication.class, args); } }

用mybatis-generator-core-1.3.7.jar 来逆向生成数据库mapper和po类

直接用注解的形式写代码。方便快捷。

package com.xukai.mapper; import com.xukai.po.Personnel; import java.util.List; import org.apache.ibatis.annotations.Select; public interface PersonnelMapper { @Select("SELECT * FROM personnel WHERE PersonnelId = #{id}") Personnel getPersonnelById(String id); @Select("select * from personnel") List<Personnel> selectAll(); @Select("select Password from OperPw where PersonId = #{id}") String getPWDByID(String id); }

这是控制器

package com.xukai.controller; import java.rmi.RemoteException; import java.util.HashMap; import java.util.Map; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import com.fasterxml.jackson.core.JsonProcessingException; import com.fasterxml.jackson.databind.ObjectMapper; import com.xukai.mapper.PersonnelMapper; import com.xukai.po.Personnel; //这个注解是不返回页面，而是返回json数据 @RestController public class LoginController { @Autowired private PersonnelMapper personnelMapper; @RequestMapping(value = "login", method = RequestMethod.POST) public String helloWorld(@RequestBody Map<String, String> maps) throws JsonProcessingException, RemoteException { ObjectMapper objectMapper = new ObjectMapper(); Map<String, String> map = new HashMap<>(); String resultString; String username = maps.get("username"); String password = maps.get("password"); //查询是否已经关联 Personnel personnel = personnelMapper.getPersonnelById(username); if (personnel == null) { map.put("success", "0"); map.put("reason", "无此账号!"); resultString = objectMapper.writeValueAsString(map); } else { String encryptPWD = personnelMapper.getPWDByID(personnel.getPersonnelid()); personnel.setEncryptPWD(encryptPWD); personnel.setPassword(pwd); //判断密码是否正确 if (password.equals(pwd)) { resultString = objectMapper.writeValueAsString(personnel); } else { map.put("success", "0"); map.put("reason", "密码不正确!"); resultString = objectMapper.writeValueAsString(map); } } return resultString; } }

OK。项目配置完了。快吧？ 而且不用tomcat就可以直接运行。
