springboot整合ssm（mybatis）
1.创建工程
使用idea可以快速创建SpringBoot的工程
这里选择常用的类库，SpringBoot将各种框架类库都进行了封装，可以减少pom文件中的引用配置：
比如Spring和Mybatis整合的时候，传统Spring项目中需要引入：
dependency
groupIdorg.mybatis/groupId
artifactIdmybatis/artifactId
version3.4.1/version
/dependency
dependency
groupIdorg.mybatis/groupId
artifactIdmybatis-spring/artifactId
version1.3.1/version
/dependency
而在SpringBoot中引入的是：
dependency
groupIdorg.mybatis.spring.boot/groupId
artifactIdmybatis-spring-boot-starter/artifactId
version1.3.1/version
/dependency
可以看到这个类库中除了mybatis和mybatis-spring之外，还有spring-boot的东西
完整的pom.xml如下:
parent

artifactIdspring-boot-starter-parent/artifactId
version1.5.10.RELEASE/version

/parent

完整的工程路径如下：
2.实体类和DAO
publicclassDept{
privateIntegerid;
privateStringname;
//getter/setter方法略
}
publicinterfaceDeptDAO{
//查询列表，演示使用传统的mapper映射文件
ListDeptgetDeltList();
//插入，演示使用注解编写sql，省略xml配置
Insert("insertintoDEPT(NAME)values(#{name})")Options(useGeneratedKeys=true,keyProperty="id",keyColumn="ID")voidaddDept(Stringname);
}
DeptMapper.xml
?xmlversion="1.0"encoding="UTF-8"?
!DOCTYPEmapperPUBLIC"-//mybatis.org//DTDMapper3.0//EN""
