求一个单纯springMVC连接数据库进行增删改查的demospringMVC

Answer 1

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
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">    <!-- 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(
        "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;
            }
        });
