休眠OneToMany关系内部连接

我试图简单地筛选出基于OneToMany关系中的子类的ID属性的结果，但Hibernate（4.1.9.Final）正在生成左外连接而不是内连接加入并因此返回我不想要的结果。休眠OneToMany关系内部连接

型号：

家长：

@Entity 
@Table(name = "CATEGORY") 
public class Category 
{ 
    @Id 
    @Column(name = "CATEGORYID") 
    private int ID; 

    @Column(name = "CATEGORYNAME") 
    private String name; 

    @OneToMany(fetch = FetchType.EAGER) 
    @JoinColumn(name = "CATEGORYID") 
    @Filter(name = "TEST_RUN_ID_FILTER") 
    private Collection<TestCase> testCases 
... 
}

儿童：

@Entity 
@Table(name = "TESTCASE_NEW") 
@FilterDef(name = "TEST_RUN_ID_FILTER", defaultCondition = "TESTRUNID in (:IDS)", parameters = { @ParamDef(name = "IDS", type = "int") }) 
public class TestCase 
{ 
    @Id 
    @Column(name = "TESTCASEID") 
    private int ID; 

    @Column(name = "TESTCASENAME") 
    private String name; 

    @Column(name = "STATUS") 
    private String status; 

    @Column(name = "TESTRUNID") 
    private int testRunId; 
... 
    }

DAO：

public List<Category> getAllCategoriesForTestRuns(List<Integer> testRunIDs) 
    { 
     Session session = getSession(); 
     session.enableFilter("TEST_RUN_ID_FILTER") 
       .setParameterList("IDS", testRunIDs); 
     Query query = session.createQuery("FROM " + Category.class.getSimpleName()); 
     List<Category> result = query.list(); 
     return resul2t; 
    }

我如何告诉Hibernate使用内部连接？

你可以试一下如下：

select c from Category c inner join c.testCases tc
