为什么80%的码农都做不了架构师？>>> 
##实例
public interface UserRoleDao extends JpaRepository<UserRole, Long> {
@Modifying
@Query(value = "INSERT INTO user_role (id, userid,roleid) " +
"VALUES (func_nextid('user_role'),?1, ?2)", nativeQuery=true)
void insert(Long userId, Integer roleId);
}
##加上transaction调用
@Test
@Transactional("demoTransactionManager")
public void testInsert(){
Long rs = userRoleDao.insert(232L,123);
System.out.println("result:"+rs);
}
