HSQLDB导致java.lang.NullPointerException的唯一约束

时间：2017-01-12 12:04:28

标签： java hibernate jpa hsqldb liquibase

当测试我添加到表中的唯一约束时，它会被遵守，但是当我尝试创建另一个打破约束的实体时，我会得到一个NullPointerException而不是约束异常或者类似物，这似乎不对

我正在使用liquibase：

<changeSet id="some-id">
    <addUniqueConstraint columnNames="PRIMARY_CODE, SECONDARY_CODE"
                         tableName="FOO"
                         constraintName="CODE_CONSTRAINT"/>
</changeSet>

但也尝试直接创建约束但获得相同的结果

ALTER TABLE FOO
add CONSTRAINT c1 UNIQUE (PRIMARY_CODE, SECONDARY_CODE);

我还使用JPA注释

在我的实体类中定义了约束 
@Entity
@Table(name = "FOO",
        uniqueConstraints = @UniqueConstraint(columnNames = { "PRIMARY_CODE", "SECONDARY_CODE" }, name = "CODE_CONSTRAINT") )
@Data
public class Foo {

我在这里缺少什么？
