求一个单纯springMVC连接数据库进行增删改查的demo springMVC --------------------编程问答-------------------- 第一，配置<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="

http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context

<!-- Scans within the base package of the application for @Components to configure as beans -->
<context:component-scan base-package="org.springframework.docs.test" />
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
<context:property-placeholder location="jdbc.properties"/>
</beans>
第二，获取jdbc模板对象
@Repository
public class JdbcCorporateEventDao implements CorporateEventDao {
private JdbcTemplate jdbcTemplate;
@Autowired
public void setDataSource(DataSource dataSource) {
this.jdbcTemplate = new JdbcTemplate(dataSource);
}
// JDBC-backed implementations of the methods on the CorporateEventDao follow...
}
第三，使用之：
this.jdbcTemplate.update(--------------------编程问答-------------------- http://download.csdn.net/detail/yeness/5625619 --------------------编程问答-------------------- 可以再网上查一下spring 托管 hibernate ，连接数据库 --------------------编程问答-------------------- 给你发送demo不太方便 --------------------编程问答-------------------- 话说刚好整合过一个。。。 --------------------编程问答-------------------- 老师布置的作业你怎么可以到论坛来求答案呢
"insert into t_actor (first_name, last_name) values (?, ?)",
"Leonor", "Watling");
this.jdbcTemplate.update(
"update t_actor set last_name = ? where id = ?",
"Banjo", 5276L);
this.jdbcTemplate.update(
"delete from actor where id = ?",
Long.valueOf(actorId));
int rowCount = this.jdbcTemplate.queryForObject("select count(*) from t_actor", int.class);
List<Actor> actors = this.jdbcTemplate.query(
"select first_name, last_name from t_actor",
new RowMapper<Actor>() {
public Actor mapRow(ResultSet rs, int rowNum) throws SQLException {
Actor actor = new Actor();
actor.setFirstName(rs.getString("first_name"));
actor.setLastName(rs.getString("last_name"));
return actor;
}
});
补充：Java , Java EE
