我是 JPA 的新手，我正在尝试调用 DB2 存储过程。但是，据我所知，正在生成的 SQL 是错误的，因此它失败了。
这是我如何设置存储过程：
@NamedStoredProcedureQuery(name = "getApplVars", procedureName = "prc_get_all_appl_var", resultClasses = ApplVars.class,
parameters = {@StoredProcedureParameter(mode = ParameterMode.IN, name = "ip_cus_set_c", type = String.class),
@StoredProcedureParameter(mode = ParameterMode.IN, name = "ip_cps_ver_n", type = Integer.class),
@StoredProcedureParameter(mode = ParameterMode.OUT, name = "op_sqlstate", type = String.class),
@StoredProcedureParameter(mode = ParameterMode.OUT, name = "op_sqlcode", type = Integer.class),
@StoredProcedureParameter(mode = ParameterMode.OUT, name = "op_msg", type = String.class)})
这是我调用存储过程的代码：
EntityManagerFactory emf = Persistence.createEntityManagerFactory("DB1");
EntityManager em = emf.createEntityManager();
StoredProcedureQuery spq = em.createNamedStoredProcedureQuery("getApplVars");
spq.setParameter("ip_cus_set_c","CONS");
spq.setParameter("ip_cps_ver_n",500);
spq.getResultList();
根据我在单步执行代码时看到的内容以及日志中的内容，这是我看到的 sql 语句。
调用 prc_get_all_appl_var(ip_cus_set_c = ?, ip_cps_ver_n = ?, op_sqlstate = ?, op_sqlcode = ?, op_msg = ?)
但应该是
调用 prc_get_all_appl_var("CONS",500,?,?,?)
这是堆栈跟踪。
