jdbctemplate

i am using hsqldb as my database. i want whenerver my select query, update query execute it will shutdown a database. below is the method in which i need a code from which i can manually shutdown my database. private void insertInitData(BasicDataSource dataSource, int lmexAdapterId, int lmsId) { try { JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource); String lmexPostParam_id = UUID.randomUUID().toString(); String inertQuery = "Insert into lmex_post_param (lmex_post_param_id, param_name, param_value) values (?,?,?)"; String[] baseUrlParam = { lmexPostParam_id, "base_url",

I have two classes class Deptartment{ int deptid, String deptname; List<Employee> employees; } class Employee{ int empid; String empname; int deptid; } Table: Department: deptid,deptname Employee empid,empname,deptid Query: select * from deptartment d,employee e where d.deptid= e.deptid Now how can i populate Department object using spring jdbc template? To help Sean Patrick Floyd, here's his solution with a single query : final Map<Integer, Department> departments = new HashMap<Integer, Department>(); this.jdbcTemplate.query( "select d.deptid, d.deptname, e.empid, e.empname from Department d

I am using Spring JDBCTemplate to conneect DB. When I am selecting date in DB using below query select to_date(valid_to,'DD-MM-YYYY HH24:MI:SS') from composition output is, 31-12-99 23:59:59. But, when I am using the same with JDBCTemplate like below, Date d = jdbcTemplate.queryForObject("select to_date(valid_to,'DD-MM-YY HH24:MI:SS') from composition",Date.class); outpt is 2099-12-31 00:00:00.0. Time is not correct. I also need the same time in Date class. How to get that? You need to use java.sql.Timestamp . java.sql.Date does not have a time component, so its time is always 00:00:00. java

Spring对数据库的操作在jdbc上面做了深层次的封装，提供了JdbcTemplate模板。 在SpringBoot使用JdbcTemplate很简单： 引入数据库驱动包（mysql或oracle） spring-boot-starter-jdbc依赖（引入了HikariCP数据连接池和spring-jdbc） 在application.yml中添加数据库配置 pom.xml配置： <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <!-- mysql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.48</version> </dependency> application.yml配置： spring: datasource: url: jdbc:mysql://192.168.178.5:12345/cloudDB01?useUnicode=true&characterEncoding=UTF-8 username: root

I'm new to Java. I've only been programming it for about a year. What does Spring mean by the use of templates? In Spring, there is jdbc-templates, jms-templates etc.. What are template classes in java? Are they a special kind of design pattern or what? Thank you in advance. They are called template as use the Template method pattern. http://en.wikipedia.org/wiki/Template_method_pattern Basically the idea is define the operation needed to do something in an abstract class or super class then implement a class that use the operation previous defined. In the case of spring allow that operation

I have a web app on Tomcat, which handles DB connection pooling, and using Spring JDBCTemplate for executing queries. It's been requested that I implement a status page which will be monitored by a heartbeat process to determine if everything is healthy with the server. As part of this, I want to do a DB query to determine if the connection to the database is ok. Ideally, since it'd just be a 'select 1 from ', I'd want it to come back fast, within 10 seconds, to indicate a failure if the DB didn't respond in that time. However, I don't want to change my connection to time out that quickly for

For many reasons I prefer not to disclose (long and boring story), I need to capture the interactions of a complex application with the Database. The application builds on top of Spring/JdbcTemplate and I need to find all the SQL sent out by this application. How can I do that in the simplest possible way? Creating a pseudo mock implementation of JdbcTemplate does not seem reasonable. First off JdbcTemplate is a class and not an interface. Second it has a large interface that makes it tedious to implement. I am thinking along the lines of mocking DataSource and Connection to get all the SQL

JdbcTemplate主要提供以下五类方法： execute方法：可以用于执行任何SQL语句，一般用于执行DDL语句； update方法及batchUpdate方法：update方法用于执行新增、修改、删除等语句；batchUpdate方法用于执行批处理相关语句； query方法及queryForXXX方法：用于执行查询相关语句； call方法：用于执行存储过程、函数相关语句。 JdbcTemplate类支持的回调类： 预编译语句及存储过程创建回调：用于根据JdbcTemplate提供的连接创建相应的语句； PreparedStatementCreator：通过回调获取JdbcTemplate提供的Connection，由用户使用该Conncetion创建相关的PreparedStatement； CallableStatementCreator：通过回调获取JdbcTemplate提供的Connection，由用户使用该Conncetion创建相关的CallableStatement； 预编译语句设值回调：用于给预编译语句相应参数设值； PreparedStatementSetter：通过回调获取JdbcTemplate提供的PreparedStatement，由用户来对相应的预编译语句相应参数设值； BatchPreparedStatementSetter：
