        功能:

        方便后续查阅.

        1.JdbcTemplate调用存储过程(Procedure)不带返回值

        1.1存储过程

        CREATE OR REPLACE PROCEDURE PRO_QUERY_INFO_ARGS4(TASK_ID IN NUMBER) IS
        BEGIN
          INSERT INTO F_LOG_INFO
            (TASK_ID,
             BEGIN_TIME,
             END_TIME,
             FLAG,
             FAIL_INFO,
             DATA_COUNT,
             TABLE_NAME)
          VALUES
            (TASK_ID, SYSDATE - 1, SYSDATE, '999', '999', 999, 'TABLE_NAME2019');
          COMMIT;
        EXCEPTION
          WHEN OTHERS THEN
            ROLLBACK;
        END PRO_QUERY_INFO_ARGS4;

        1.2代码

        public static void doProcedures() {
        	String procedures = "{call PRO_QUERY_INFO_ARGS4 ('888')}";
        	jdbcTemplate.execute(procedures);
        }

        2.JdbcTemplate调用存储过程(Procedure)带返回值但值不是集合类型

        2.1存储过程

        CREATE OR REPLACE PROCEDURE PRO_QUERY_INFO_ARGS3(ARGS     IN VARCHAR2,
                                                         RTNINFO  OUT VARCHAR2,
                                                         ERRORMSG OUT VARCHAR2,
                                                         FAILINFO OUT VARCHAR2) IS
        BEGIN
          ERRORMSG := '';
          RTNINFO  := '你输入的ARGS=' || ARGS;
          SELECT FAIL_INFO编程客栈 INTO FAILINFO FROM F_LOG_INFO where TASK_ID = 1;
          COMMIT;
        EXCEPTION
          WHEN OTHERS THEN
            ERRORMSG := 'PRO_QUERY_INFO_ARG抛出异常: ' || SQLERRM;
        END PRO_QUERY_INFO_ARGS3;

        2.2代码

        public static void getProceduresResult() {
          String tt2 = (String) jdbcTemplate.execute(
          new CallableStatementCreator() {
          	public CallableStatement createCallableStatement(
          	  	Connection con) throws SQLException {
          	  String procedures = "{call PRO_QUERY_INFO_ARGS3 (?,?,?,?)}";
          	  CallableStatement cs = con.prepareCall(procedures);
          	  /** 设置输入参数的值 */
          	  cs.setString(1, "代码调用");
          	  /** 注册输出参数的类型-此处集合为oracle的VARCHAR2 */
          	  cs.registerOutParameter(2, OracleTypes.VARCHAR);
          	  cs.registerOutParameter(3, OracleTypes.VARCHAR);
          	  cs.registerOutParameter(4, OracleTypes.VARCHAR);
          	  return cs;
          	}
          }, new CallableStatementCallback() {
          	public Object doInCallableStatement(CallableStatement st)
          	  	throws SQLException, DataAccessException {
          	  st.execute();
          	  /** 依次获取存储过程参数值,按照顺序存储过程定义参数的顺序获取 */
          	  Object tt2 = st.getObject(2);
          	  Object tt3 = st.getObject(3);
          	  Object tt4 = st.getObject(4);
          	  return tt2;
          	}
        	});
        }

        3.JdbcTemplate调用存储过程(Procedure)带返回值且值集合类型

        3.1存储过程

        CREATE OR REPLACE PROCEDURE PRO_QUERY_INFO_ARGS2(ERRORMSG OUT VARCHAR2,
                                                         CURINFO  OUT SYS_REFCURSOR) IS
        BEGIN
          ERRORMSG := '';
          OPEN CURINFO FOR
            SELECT FAIL_INFO, TABLE_NAME FROM F_LOG_INFO;
          COMMIT;
        EXCEPTION
          WHEN OTHERS THEN
            ERRORMSG := 'PRO_QUERY_INFO_ARG2抛出异常: ' || SQLERRM;
        END PRO_QUERY_INFO_ARGS2;

        3.2代码

        public static List getProceduresResultList() {
         
         List resultList = (List) jdbcTemplate.execute(
          new CallableStatementCreator() {
          	public CallableStatement createCallableStatement(
          	  	Connection conn) throws SQLException {
          	  /** 调用指定存储过程 */
          	  String procedures = "{ CALL PRO_QUERY_INFO_ARGS2(?,?) }";
          	  CallableStatement statement = conn
          	  		.prepareCall(procedures);
          	  /** 注册输出参数的类型-此处集合为oracle的VARCHAR2 */
          	  statement.registerOutParameter(1, OracleTypes.VARCHAR);
          	  /** 注册输出参数的类型-此处集合为oracle的游标类型 */
          	  statement.registerOutParameter(2, OracleTypes.CURSOR);
          	  return statement;
          	}
          }, new CallableStatementCallback() {
          	public Object doInCallableStatement(
          	  	CallableStatement statement) throws SQLException,
          	  	DataAccessException {
          	  List resultsMap = new ArrayList();
          	  statement.execute();
          	  /** 获取游标结果集-此处2是存储过程参数顺序 */
          	  ResultSet resultSet = (ResultSet) statement
          	  		.getObject(2);
          	  /** 转换每行的返回值到Map中 */
          	  while (resultSet.next()) {
          	  	Map rowMap = new HashMap();
          	  	rowMap.put("FAIL_INFO",
          	  			resultSet.getObject("FAIL_INFO"));
          	  	rowMap.put("TABLE_NAME",
          	  			resultSet.getObject("TABLE_NAME"));
          	  	resultsMap.add(rowMap);
          	  }
          	  resultSet.close();
          	  return resultsMap;
          	}
          });
         return resultList;
        }

        4.附本例使用建表语句

        create table F_LOG_INFO
        (
          task_id    NUMBER(16) not null,
          begin_time DATE,
          end_time   DATE,
          flag       VARCHAR2(8),
          fail_info  VARCHAR2(512),
          data_count NUMBER(16),
          table_name VARCHAR2(256)
        );
        alter table F_LOG_INFO
          add constraint PK_F_LOG_INFO primary key (TASK_ID);

        5.附本例使用完整测试代码

        public class TestProcedures {
        public static JdbcTemplate jdbcTemplate = getJdbcTemplate();
        public static void main(String[] args) {
         System.out.println("测试开始......");
         // getProceduresResult();
         doProcedures();
         List result = getProceduresResultList();
         for (int i = 0; i < result.size(); i++) {
          Map rowMap = (Map) result.get(i);
          String id = rowMap.get("FAIL_INFO")js.toString();
          String name = rowMap.get("TABLE_NAME").toString();
          System.out.println("FAIL_INFO=" + id + ";TABLE_NAME=" + name);
         }
         System.out.println("测试结束......");
        }
        /**

        public static void doProcedures() {
        	String procedures = "{call PRO_QUERY_INFO_ARGS4 开发者_Go学习('888')}";
        	jdbcTemplate.execute(procedures);
        }
        /**
         * 调用存储过程-返回值是非集合
         * */
        public static void getProceduresResult() {
         String tt2 = (String) jdbcTemplate.execute(
          new CallableStatementCreator() {
          	public CallableStatement createCallableStatement(
          	 	Connection con) throws SQLException {
          	 String procedures = "{call PRO_QUERY_INFO_ARGS3 (?,?,?,?)}";
          	 CallableStatement cs = con.prepareCall(procedures);
          	 /** 设置输入参数的值 */
          	 cs.setString(1, "代码调用");
          	 /** 注册输出参数的类型-此处集合为oracle的VARCHAR2 */
          	 cs.registerOutParameter(2, OracleTypes.VARCHAR);
          	 cs.registerOutParameter(3, OracleTypes.VARCHAR);
          	 cs.registerOutParameter(4, OracleTypes.VARCHAR);
          	 return cs;
          	}
          }, new CallableStatementCallback() {

          	 	throws SQLException, DataAccessException {
          	 st.execute();
          	 /** 依次获取存储过程参数值,按照顺序存储过程定义参数的顺序获取 */
          	 Object tt2 = st.getObject(2);
          	 Object tt3 = st.getObject(3);
          	 Object tt4 = st.getObject(4);
          	 return tt2;
          	}
          });
        }
        /**

        public static List getProceduresResultList() {
          List resultList = (List) jdbcTemplate.execute(
           new CallableStatementCreawww.devze.comtor() {
           	public CallableStatement createCallableStatement(
           	 	Connection conn) throws SQLException {
           	 /** 调用指定存储过程 */
           	 Strin编程客栈g procedures = "{ CALL PRO_QUERY_INFO_ARGS2(?,?) }";
           	 CallableStatement statement = conn
           	 		.prepareCall(procedures);

           	 statement.registerOutParameter(2, OracleTypes.CURSOR);
           	 return statement;
           	}
           }, new CallableStatementCallback() {
           	public Object doInCallableStatement(
           	 	CallableStatement statement) throws SQLException,
           	 	DataAccessException {
           	 List resultsMap = new ArrayList();
