Error in One to many mapping in hibernate-spring integration

Question

I need to map two pojo class using one to many, but getting the below error com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column 'testCaseStepsform' at row 1

When I saw the table created by hibernate, I found that a column with data type blob is created

I am adding the code below.

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

    /**

Answer 1

You should choose to annotate object properties or getters. Don't use it simultaneously.

Answer 2

Apart, @xl0e answer

You need to correct mapping

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