1.背景:T表F字段唯一索引,保存F字段重复的数据后台异常(附后),不做处理MVC框架包装异常后,前台显示"Could not execute JDBC batch update; nested exception is org.hibernate.exception...",报错信息不友好,故主动捕获后跑出友好业务相关信息"XXXXXXXXXX重复"。
2.框架:Hibernate+Spring+公司MVC。
3.异常详情:
Could not execute JDBC batch update; nested exception is org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update

4.解决过程:
so easy...直接捕获呗,从异常信息里找唯一约束索引号,如果找到不ok了嘛,代码见下:
try {
busiDAO.save(bean);
} catch(RuntimeException e) {
String errMsg = e.getMessage();
if(StringUtils.isNotBlank(errMsg) && errMsg.indexOf("IDX_T_A")!=-1) {
throw new RuntimeException("XXXXXXXXXX重复!");
}
throw e;
}
no...no...捕获不了呀,系统仍然抛底层的错误信息。
oh!e.getMessage()得到的是"Could not execute JDBC batch update; nested exception is org.hibernate.exception",获取不到唯一约束索引号,这什么状况啊?
oh!错误信息在里面了,好吧,再往里一步,代码如下:
try {
busiDAO.save(bean);
} catch(RuntimeException e) {
Throwable cause = e.getCause();
if(cause instanceof org.hibernate.exception.ConstraintViolationException) {
String errMsg = ((org.hibernate.exception.ConstraintViolationException)cause).getSQLException().getMessage();
if(StringUtils.isNotBlank(errMsg) && errMsg.indexOf("IDX_T_A")!=-1) {
throw new RuntimeException("XXXXXXXXXX重复!");
}
}
throw e;
}
ok!
5.总结:难的只是目前陌生的东西,碰过面的就不是难的了。
