使用 jOOQ 执行 PL/SQL 函数时的 Java 空指针答案

【问题标题】：Java null pointer when executing a PL/SQL function using jOOQ使用 jOOQ 执行 PL/SQL 函数时的 Java 空指针
【发布时间】：2018-12-11 22:47:33
【问题描述】：

我目前正在尝试调用一个接受多个输入/输出参数的 PL/SQL 函数。该函数包含以下数据类型：

字符串。
字符串数组。

但是，当应用程序设置数据以将其发送到数据库服务器时，应用程序会抛出 空指针异常，该异常与引起的实际错误无关（请注意，实际错误是如下所示，因为这是在调试应用程序时计算出来的）。

应用程序正在准备以下数据：

字符串 -> 这些没有问题
列表 -> 转换为 CustTabVarchar2_50Record
列表 -> 转换为 CustTabVarchar2_4000Record

然后将其传递给 jOOQ 生成的类，该类包含 PL/SQL 函数的 Java 包装器。

此时它在迭代参数时失败，特别是在迭代 CustTabVarchar2_50Record 时失败。

此时会抛出异常：

java.lang.NoSuchMethodException: No similar method createARRAY with params [class java.lang.String, class [Ljava.lang.Object;] could be found on type class org.jboss.jca.adapters.jdbc.jdk8.WrappedConnectionJDK8.

我目前假设它可能是以下问题之一：

jOOQ 的一个问题。
jBoss 使用的库不正确，因为它声明：'org.jboss.jca.adapters.jdbc.jdk8.WrappedConnectionJDK8'

PL SQL 标头：

procedure a_l_ws(
  p_i_num      in      varchar2, 
  p_s       in      varchar2,
  p_u       in      varchar2,
  p_tpu    in      varchar2,
  p_tpa     in      varchar2,
  p_data_desc     in      cust_tab_varchar2_50,
  p_l     in      cust_tab_varchar2_4000,
  p_r        out     pls_integer,
  p_p     out     varchar2,
  p_appl        out     varchar2,
  p_ml    out     cust_tab_varchar2_12,
  p_m         out     cust_tab_varchar2_4000)

【问题讨论】：

您尝试使用 createArrayOf 而不是 createARRAY 的方法不正确吗？我正在查看repository.jboss.org/nexus/content/unzip/unzip/org/jboss/… 中的文档，其中提到了具有相同签名但名称不同的类似方法。
如何创建在c.r.w.jooq.model.db.db.packages.Aim.aimLoadWs 中使用的jOOQ Configuration / DSLContext？我对您提供给 jOOQ 的 ConnectionProvider 和/或 DataSource 特别感兴趣。
另外，您使用的是什么 jOOQ 版本？调用WrappedConnectionJDK8.getUnderlyingConnection() 时是否得到OracleConnection 的实例？同时，我为此创建了一个问题：github.com/jOOQ/jOOQ/issues/7641
@LukasEder 从 jboss 配置中检索数据源。这意味着这是在 jBoss 中的standalone.xml 中预定义的，并由“jBoss EAP 7.0”创建。本例中使用的方言是“Oracle 11g”，jOOQ 版本是“3.9.4”。请注意，这曾经在 Java 7 中工作，但是随着 Java 8 的变化，情况发生了变化。
@Joseph118：您在调用 WrappedConnectionJDK8.getUnderlyingConnection() 时是否获得了 OracleConnection 的实例？这将有助于修复它。

【解决方案1】：

这似乎与https://github.com/jOOQ/jOOQ/issues/3639 相关，当使用配置了 Oracle JDBC 驱动程序的连接包装器（通过数据源或连接池）时。在您的情况下，您似乎正在使用 JBoss 数据源。如问题中所述，由于 createARRAY 不是标准 JDBC 而是特定于 Oracle，如果您使用 Oracle 方言创建 DSL 连接，jOOQ 将假定正在使用 Oracle 连接，因此尝试调用 Oracle 的 createARRAY() 而不是 createArrayOf( )。

也许 jOOQ 的作者可以阐明是否可以通过配置设置、修复或其他方式避免这种情况。

注意：必须将此作为答案而不是评论，因为我的声誉仍然很低。如果此条目获得高票，将在此处提供最终答案。

【讨论】：

ojdbc doesn't implement createArrayOf()。另见：docs.oracle.com/en/database/oracle/oracle-database/12.2/jjdbc/…
没错。从提供的堆栈跟踪来看，jOOQ 似乎试图在只包含 createArrayOf() 的 org.jboss.jca.adapters.jdbc.jdk8.WrappedConnectionJDK8 上调用 createARRAY()。 repository.jboss.org/nexus/content/unzip/unzip/org/jboss/…
当然，但它在尝试解开OracleConnection 之后这样做，显然WrappedConnectionJDK8 不支持。所以，你的分析很可能是正确的。当 Spring JDBC Connection 包装器也没有打开 OracleConnection 时，您链接的 #3639 问题非常相似。这可能是一个错误，因此请随时将github.com/jOOQ/jOOQ/issues/7641 添加到您的答案中。

【解决方案2】：

这似乎是 JBoss WrappedConnectionJDK8 的一个限制，它在调用时似乎没有正确解开 OracleConnection 类型：

OracleConnection ocn = wrapped.unwrap(OracleConnection.class);

过去，(as GilbertD has mentioned)，jOOQ 通过反射调用供应商特定的展开方法来解决这些限制，例如那些在春天通过#3639。 WrappedConnectionJDK8.getUnderlyingConnection() 也可以这样做，请参阅 #7641

解决方法

作为一种解决方法，您可以从 JBoss 提供的 JDBC Connection 包装器中手动解包 OracleConnection，并将其直接提供给 jOOQ，例如通过代理 JBoss DataSource

class WorkaroundDataSource implements DataSource {
    final DataSource delegate;

    public WorkaroundDataSource(DataSource delegate) {
        this.delegate = delegate;
    }

    @Override
    public Connection getConnection() throws SQLException {
        return unwrapOracleConnection(delegate.getConnection());
    }

    // ...
}

然后：

DSLContext ctx = DSL.using(new WorkaroundDataSource(jbossDataSource), SQLDialect.ORACLE);
