Manual commit is not allowed over a Spring managed SqlSession Manual close is not allowed over a Spring managed SqlSession
出现这种异常是因为spring在管理sqlsession对象的时候使用了代理类,通过这个代理类来实现对所有的事物实现提交以及关闭
跟踪源码我们可以发现
//这是我调用的方法,现在进入session的insert的方法内 public boolean insert(Users users) { SqlSession session = super.getSqlSession(); System.out.println(session); int insert = session.insert("com.cc.dao.UserDao.insert", users); return insert>0?true:false; } //发现原来是用代理类实现的,接着跟踪 public int insert(String statement, Object parameter) { return this.sqlSessionProxy.insert(statement, parameter); } //这是这个代理类的创建方式,于是,找到了SqlSessionInterceptor这个类 this.sqlSessionProxy = (SqlSession) newProxyInstance( SqlSessionFactory.class.getClassLoader(), new Class[] { SqlSession.class }, new SqlSessionInterceptor()); //这就是这个代理类的invoke方法,可以看到,他确实是帮我们实现了commit方法以及close方法 public Object invoke(Object proxy, Method method, Object[] args) throws Throwable { SqlSession sqlSession = getSqlSession( SqlSessionTemplate.this.sqlSessionFactory, SqlSessionTemplate.this.executorType, SqlSessionTemplate.this.exceptionTranslator); try { Object result = method.invoke(sqlSession, args); if (!isSqlSessionTransactional(sqlSession, SqlSessionTemplate.this.sqlSessionFactory)) { // force commit even on non-dirty sessions because some databases require // a commit/rollback before calling close() sqlSession.commit(true); } return result; } catch (Throwable t) { Throwable unwrapped = unwrapThrowable(t); if (SqlSessionTemplate.this.exceptionTranslator != null && unwrapped instanceof PersistenceException) { // release the connection to avoid a deadlock if the translator is no loaded. See issue #22 closeSqlSession(sqlSession, SqlSessionTemplate.this.sqlSessionFactory); sqlSession = null; Throwable translated = SqlSessionTemplate.this.exceptionTranslator.translateExceptionIfPossible((PersistenceException) unwrapped); if (translated != null) { unwrapped = translated; } } throw unwrapped; } finally { if (sqlSession != null) { closeSqlSession(sqlSession, SqlSessionTemplate.this.sqlSessionFactory); } } }
