- 增删改查模板项目,旨在减少重复代码.
- 注意: 目前只支持redis-hash的数据类型
- 单个表的数据库增删改查操作
- 单个表的数据库+缓存的增删改查操作
- 单个实体的缓存增删改查操作
- 对象比较
- Id增强查询
- 在启动类上添加如下代码
- scanPackages 用来填写需要扫描的实体包路径,支持多个
- 填写相关mapper方法名称.
@EnableCrudTemplate(
scanPackages = {
"com.github.huifer.mybatis"},
selectByIdMethodName = "selectByPrimaryKey",
deleteByIdMethodName = "deleteByPrimaryKey",
updateByIdMethodName = "updateByPrimaryKeySelective",
insertMethodName = "insertSelective") <dependency>
<groupId>com.github.huifer</groupId>
<artifactId>common</artifactId>
<version>LAST_VERSION</version>
</dependency>@CacheKey(key = "issues", type = IssuesEntity.class)
public interface IssuesMapper {}public class IssuesEntity implements BaseEntity {}public class IssuesEntity implements BaseEntity {}
- 调用层 mybatis 和 mybatis-plus 都是同一个入口
@Autowired
private CrudFacade crudFacade;
- 只需要引入
CrudFacade组件就可以拥有数据库+缓存的crud操作了. 如果不需要缓存请将mapper上的@CacheKey删掉
- 给实体对象添加注解
@CacheKey
- redis-hash field 取值说明: idFiled=实体类的某个字段, idMethod=实体类中的一个方法,
如果两者同时存在以
idMethod为准, 建议填写一个
@CacheKey(key = "tt", type = IssuesEntity.class, idFiled = "newTitle", idMethod = "ooo")
public class IssuesEntity {
private Integer id;
private String newTitle;
private String ooo() {
return "OOO" + this.newTitle;
}
}
