object references an unsaved transient instance - save the transient instance before flushing:..........
在Entity设置了单向的 ManyToMany, 级联新增的时候发现报错了
@ManyToMany(cascade = { CascadeType.REFRESH, CascadeType.MERGE }) @JoinTable(name = "t_Testcase_TestScript", joinColumns = { @JoinColumn(name = "caseId") }, inverseJoinColumns = { @JoinColumn(name = "scriptId") }) private Set<TestScript> testScripts = new HashSet<TestScript>();
原因:级联对象没有被保存
解决办法:
cascade = { CascadeType.ALL }
或者把级联对象先保存
