crud template

  • 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

功能

  • 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

如何使用

  • 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")

mybatis+mybatis-plus 支持

  • 添加依赖
    <dependency>
      <groupId>com.github.huifer</groupId>
      <artifactId>common</artifactId>
      <version>LAST_VERSION</version>
    </dependency>
  • 对mapper进行修改
@CacheKey(key = "issues", type = IssuesEntity.class)
public interface IssuesMapper  {}
  • 对实体进行修改
public class IssuesEntity implements BaseEntity {}
  • 对实体进行修改
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

entity 支持

  • 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;
  }
}
