第一个SpringBoot+MyBatis+JSR303项目

Maven的包基本就这些,现在大多数使用springboot的项目应该都是使用jdk1.8的吧，所以项目的jdk设置成1.8

配置方面是用的是yaml进行配置，所以需要引入spring-boot-configuration-processor包，配置看上去层次分明，更加直观

server:
 port: 80
spring:
 datasource:
   name: test
   url: jdbc:mysql://192.168.1.105:3306/test
   username: root
   password: 123456
   # 使用druid数据源
   type: com.alibaba.druid.pool.DruidDataSource
   driver-class-name: com.mysql.jdbc.Driver
   filters: stat
   maxActive: 20
   initialSize: 1
   maxWait: 60000
   minIdle: 1
   timeBetweenEvictionRunsMillis: 60000
   minEvictableIdleTimeMillis: 300000
   validationQuery: select 'x'
   testWhileIdle: true
   testOnBorrow: false
   testOnReturn: false
   poolPreparedStatements: true
   maxOpenPreparedStatements: 20
mybatis:
 mapperLocations: classpath:app/com/kenho/mapper/*Mapper.xml

SpringBoot的启动文件放的位置比较讲究，基本上把启动文件放在一个包下，然后项目的需要的各种累放在启动文件下的下级目录，这样启动的时候才能被扫描的到，所以控制类，服务类，dao类。就要添加上@RestController @Service @Repository注解，SpringBoot现在用REST风格比较多，所以使用的注解式@RestController他等于@ResponseBody+@Controller，其次就是控制类的bean注入最好是引用@Resource，因为@Resource是按照名字进行匹配，找不到匹配的bean才进行类型的匹配

package app.com.kenho.web.controller;

import app.com.kenho.domain.Logininfo;
import app.com.kenho.service.ILoginService;
import app.com.kenho.service.impl.LoginServiceImpl;
import org.springframework.validation.BindingResult;
import org.springframework.validation.ObjectError;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import javax.naming.Binding;
import javax.validation.Valid;
import java.util.List;

/**
 * Created by Stephanie on 2017/8/19.
 */
@RestController
public class indexController {
    @Resource
    private ILoginService loginServiceImpl;

    @RequestMapping(value = "logininfo/{username}/{password}",method = RequestMethod.GET)
    public Logininfo getlogininfo(@PathVariable("username")String username,@PathVariable("password")String password)
    {
        //loginServiceImpl.getLoginInfo("stephanie","81DC9BDB52D04DC20036DBD8313ED055");
        return loginServiceImpl.getLoginInfo(username,password);
    }

    @RequestMapping(value = "logininfo",method = RequestMethod.POST)
    public void valid(@Validated Logininfo logininfo, BindingResult bindingResult)
    {
        if(bindingResult.hasErrors())
        {
            List<ObjectError> list = bindingResult.getAllErrors();
            StringBuilder stringBuilder = new StringBuilder();
            for(ObjectError  error:list){
                System.out.println("\n"+error.getDefaultMessage());
            }
        }
        else
        {
            loginServiceImpl.insert(logininfo);
        }
    }
}
