spring的JdbcTemplate操作oracle的存储过程

场景:
    使用java代码调用oracle的存储过程,本例使用JdbcTemplate模板类操作.
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 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").toString();   String name = rowMap.get("TABLE_NAME").toString();   System.out.println("FAIL_INFO=" + id + ";TABLE_NAME=" + name);  }  System.out.println("测试结束......"); } /**  * 执行存储过程无返回值  * */ public static void doProcedures() { 	String procedures = "{call PRO_QUERY_INFO_ARGS4 ('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() {   	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;   	}   }); } /**  * 调用存储过程-返回值是List集合  * */ 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; } /** 获取JdbcTemplate数据源 */ public static JdbcTemplate getJdbcTemplate() {   DruidDataSource dataSource = new DruidDataSource();   /**数据库连接信息*/   String username = "demodb";   String password = "123456";   String jdbcUrl = "jdbc:oracle:thin:@127.0.0.1:1521/orcl";   String driverName = "oracle.jdbc.OracleDriver";   /** 设置数据源属性参数 */   dataSource.setPassword(password);   dataSource.setUrl(jdbcUrl);   dataSource.setUsername(username);   dataSource.setDriverClassName(driverName);   /** 获取spring的JdbcTemplate*/   JdbcTemplate jdbcTemplate = new JdbcTemplate();   /** 设置数据源 */   jdbcTemplate.setDataSource(dataSource);   return jdbcTemplate; } }

以上,感谢.
