jdbcTemplate调用储存过程

 JdbcTemplate调用Oracle存储过程的一些方法:

1、 无返回值的存储过程调用:

public class JdbcTemplateTest { 
  private JdbcTemplate jdbcTemplate; 
  public void setJdbcTemplate(JdbcTemplate jdbcTemplate) { 
  this.jdbcTemplate = jdbcTemplate; 
  } 
  public void test(){ 
     this.jdbcTemplate.execute("call testpro('p1','p2')"); 
  } 
} 

2、有返回值的存储过程(非结果集)

public void test() { 
  String param2Value = (String) jdbcTemplate.execute( 
     new CallableStatementCreator() { 
        public CallableStatement createCallableStatement(Connection con) throws SQLException { 
           String storedProc = "{call testpro(?,?)}";// 调用的sql 
           CallableStatement cs = con.prepareCall(storedProc); 
           cs.setString(1, "p1");// 设置输入参数的值 
           cs.registerOutParameter(2, OracleTypes.VARCHAR);// 注册输出参数的类型 
           return cs; 
        } 
     }, new CallableStatementCallback() { 
         public Object doInCallableStatement(CallableStatement cs) throws SQLException, DataAccessException { 
           cs.execute(); 
           return cs.getString(2);// 获取输出参数的值 
     } 
  }); 
} 

3、有返回值的存储过程(结果集)

1.建一个程序包,如下: 
CREATE OR REPLACE PACKAGE TESTPACKAGE AS 
  TYPE TEST_CURSOR IS REF CURSOR; 
END TESTPACKAGE; 
2.建立存储过程,如下: 
CREATE OR REPLACE PROCEDURE TESTPRO(PARAM1 IN VARCHAR2,test_cursor out TESTPACKAGE.TEST_CURSOR) IS 
BEGIN 
     OPEN test_cursor FOR SELECT * FROM TESTTABLE; 
END TESTPRO; 
可以看到,列表是通过把游标作为一个out参数来返回的。

java测试代码:

public void test() { 
  List resultList = (List) jdbcTemplate.execute( 
     new CallableStatementCreator() { 
        public CallableStatement createCallableStatement(Connection con) throws SQLException { 
           String storedProc = "{call testpro(?,?)}";// 调用的sql 
           CallableStatement cs = con.prepareCall(storedProc); 
           cs.setString(1, "p1");// 设置输入参数的值 
           cs.registerOutParameter(2, OracleTypes.CURSOR);// 注册输出参数的类型 
           return cs; 
        } 
     }, new CallableStatementCallback() { 
        public Object doInCallableStatement(CallableStatement cs) throws SQLException,DataAccessException { 
           List resultsMap = new ArrayList(); 
           cs.execute(); 
           ResultSet rs = (ResultSet) cs.getObject(2);// 获取游标一行的值 
           while (rs.next()) {// 转换每行的返回值到Map中 
              Map rowMap = new HashMap(); 
              rowMap.put("id", rs.getString("id")); 
              rowMap.put("name", rs.getString("name")); 
              resultsMap.add(rowMap); 
           } 
           rs.close(); 
           return resultsMap; 
        } 
  }); 
  for (int i = 0; i < resultList.size(); i++) { 
     Map rowMap = (Map) resultList.get(i); 
     String id = rowMap.get("id").toString(); 
     String name = rowMap.get("name").toString(); 
     System.out.println("id=" + id + ";name=" + name); 
  } 
}
