Question

我正在尝试在JPA Repository中添加两个相同的方法名称。我不确定是否可能。

这就是我在JPA界面中实际尝试做的事情：

public interface TbiDDCustomQueryConfigDao extends CrudRepository<TbiDDCustomQueryConfig, Integer>, JpaRepository<TbiDDCustomQueryConfig, Integer>{

    @Query("select c from TbiDDCustomQueryConfig c, TbiDataSource d where c.datasourceId= d.dataSourceId and c.tbiDDConfigMaster.ddConfigId = ?1 and c.isActive = ?2 and d.isActive='Y'")
    List<TbiDDCustomQueryConfig> findByDdConfigIdAndIsActive(Integer ddConfigId,String isActive);

    TbiDDCustomQueryConfig findByDdConfigIdAndIsActive(Integer ddConfigId,String isActive);

}

编译错误告诉我重命名该方法。我改变了第二种方法如下：

TbiDDCustomQueryConfig findByDdConfigIdAndIsActive1(Integer ddConfigId,String isActive);

但是当我运行代码时，我收到了错误：

Answer 1

您不能使用相同的名称使用相同的参数。 Java不允许这样做。如果重命名由spring-data-jpa自动解释的lower方法，它将无效。未使用@Query注释的方法由其名称解释。重命名它会导致像您这样的错误，它无法找到属性。 IsActive1不存在，例如

解决方案：重命名upper方法并确保实体中存在所有属性。特别是因为它说： No property dd found for type TbiDDCustomQueryConfig!

你可能想要findByIdAndIsActive或类似的东西。

Answer 2

我不认为问题来自上层

findByDdConfigIdAndIsActive (Integer ddConfigId,String isActive);

我有相同的方法

findByParentGroupIdIsNullAndDeleted(boolean deleted); //parentGroupId , deleted

它工作正常。 spring data jpa认为'DdConfigId'为'dd'所以Config是问题所在，也许spring数据采用'config'之类的关键字表达式与'AND'和'OR'相同

jpa存储库有2种相同的方法
