jdbctemplate

问题 Using Spring's JdbcTemplate, I've been trying to figure out a clean way to log exceptions in the DAO layer, but can't seem to figure it out. I want to log the SQL statement that was used and the parameters. For example, where addStoreSql is a parameterized statement public int addStore(Store store) { return jdbcTemplate.update(addStoreSql, store.getId(), store.getName()); } I'm doing something like.. public int addStore(Store store) { try{ return jdbcTemplate.update(addStoreSql, store.getId()

问题 While reading from database the logs in my dao class shows junk characters in place of unicode characters. Sql developer shows correct values from oracle database also correct NLS language encoding is set on the database. Below code works for standard jdbc: connection = DriverManager.getConnection( "jdbc:oracle:thin:@localhost:1521:xe", "adminuser", "oracle"); Statement st=connection.createStatement(); ResultSet res=st.executeQuery("SELECT menu_item_name from pending_menu_item where menu_item

问题 I am using spring jdbc template, to create record using stored procedure public Long create(City $obj) { SimpleJdbcCall jdbcCall = new SimpleJdbcCall(getJdbcTemplate().getDataSource()).withProcedureName(SP_ADD_UPDATE); jdbcCall.declareParameters(new SqlOutParameter(ConstantUtil.RETUR_VAL, OracleTypes.BIGINT)); Map<String, Object> jdbcCallResult = jdbcCall.execute(new MapSqlParameterSource(populateParams($obj))); return (Long) jdbcCallResult.get(ConstantUtil.RETUR_VAL); } params private static

问题 I have some queries like this: List listOfIntegers = Arrays.asList(new Integer[] {1, 2, 3}); List objects = namedParameterJdbcTemplate.query("select * from bla where id in ( :ids )", Collections.singletonMap("ids", listOfIntegers), myRowMapper); This will send this SQL query to the database: select * from bla where id in ( 1, 2, 3 ) Now I want to send this type of query to the database: select * from bla where (id,name) in ( (1,'foo'), (2,'bar'), (3,'foobar')) Do I need to pass a List<List

问题 I'm trying to accommodate to Spring JDBC, but what bugs me is using these anonymous classes, where we cannot pass any local variables unless they are final which might be easy to arrange, but what about if I need to loop an array or collection ? I cannot declare "FedModel fm" to be final as it gets reinitialized in the loop, but I need to call the execute method 100 times. This is concrete scenario where I have the problem, cause I don't know any other way how to insert BLOB into a database.

问题 Trying to do an insert, I have: jdbcTemplate.update("insert into....", new Object[]{foo.getId(), foo.getName()}) foo.getId() returns a long, and getName() a String. I have "NUMBER" as the id type in Oracle, and varchar2 for the name field. I'm getting SQLtype unknown problem. the update method has a version where I do not have to put in the SQL types, but do I have to, and if so, how? 回答1: I'm assuming you mean the Spring Framework JdbcTemplate class. The JdbcTemplate methods will attempt to

问题 My Spring Boot 1.3.2.RELEASE app is using both Hibernate and JDBC (using JdbcTemplate). This is running on Java 8. The JDBC driver is Oracle ojdbc7 12.1.0.1. It is configured to use Spring connection pooling. I recently switched from c3p0 which worked. When I test the new configuration (no c3p0) it under load, it quickly allocates all the connections I set it to (max 50, I used netstat to count) and then I start to see many abandoned connection exceptions. Then I start to get exceptions
