# 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](./doc/object-compare.md)
- [Id增强查询](./doc/增强类查询.md)

## 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. 
```java
@EnableCrudTemplate(
    scanPackages = {
        "com.github.huifer.mybatis"},
    selectByIdMethodName = "selectByPrimaryKey",
    deleteByIdMethodName = "deleteByPrimaryKey",
    updateByIdMethodName = "updateByPrimaryKeySelective",
    insertMethodName = "insertSelective")

```

### mybatis+mybatis-plus 支持
- 添加依赖  

```xml
    <dependency>
      <groupId>com.github.huifer</groupId>
      <artifactId>common</artifactId>
      <version>LAST_VERSION</version>
    </dependency>
```

- 对mapper进行修改
```java
@CacheKey(key = "issues", type = IssuesEntity.class)
public interface IssuesMapper  {}
```

- 对实体进行修改

```java
public class IssuesEntity implements BaseEntity {}
```




- 对实体进行修改

```java
public class IssuesEntity implements BaseEntity {}
```


- 调用层 mybatis 和 mybatis-plus 都是同一个入口

```java
  @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
    
    
```java
@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;
  }
}
```
