spring框架设置jdbc

Posted 2021-05-07 肖镜泽

1.导包

com.springsource.org.apache.commons.dbcp-1.2.2.osgi.jar
com.springsource.org.apache.commons.pool-1.5.3.jar
mysql-connector-java-5.1.26-bin.jar

 

2.配置BasicDataSource对象（在spring的核心配置文件中设置）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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" >
     
    <!--  引入jdbc.properties -->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
    </bean>
    
</beans>

3.配置jdbc配置文件（jdbc.properties文件）

jdbc.username=数据库账号
jdbc.password=数据库密码
jdbc.url=jdbc:mysql:///数据库名
jdbc.driverClassName=com.mysql.jdbc.Driver

4.测试

@RunWith(SpringJUnit4ClassRunner.class)
//加载spring核心xml文件
//@ContextConfiguration("classpath:applicationContext.xml")
@ContextConfiguration
public class TestMain {
    //Autowired将对象地址自动注入到变量dataSource里
    @Autowired
    private DataSource dataSource;
    
  
    @Test
    public void test() throws SQLException{
        Connection connection = dataSource.getConnection();
        PreparedStatement ps = connection.prepareStatement("insert into 表名(字段1,字段2) values(?,?)");
        ps.setObject(1, "澳大利亚");
        ps.setObject(2,7);
        ps.executeUpdate();
    }
}
