Java hibernate spring集成中的一对多映射出错

我需要使用一对多映射两个pojo类，但得到以下错误 com.mysql.jdbc.MysqlDataTruncation:数据截断：第1行“testCaseStepsform”列的数据太长

当我看到hibernate创建的表时，我发现创建了一个数据类型为blob的列

我在下面添加代码

@Entity
@Table(name="TEST_CASE_DESC")
public class TestCaseForm implements Serializable{

    /**
     *

    private static final long serialVersionUID = 10001234L;

您应该选择注释对象属性或getter。不要同时使用它。

分开，@xl0e回答

您需要更正映射

@OneToMany(mappedBy = "testCaseForm", cascade = CascadeType.ALL)
public ArrayList<TestCaseStepsForm> getTestCaseStepsform() {
    return testCaseStepsform;
}
