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......"); } /** * 执行存储过程无返回值 * */ 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() { 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 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); /** 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 JdbcTemawNpxplate(); /** 设置数据源 */ jdbcTemplate.setDataSource(dataSource); return jdbcTemplate; } }
