[记录我上课找的bug]有关spring....

applicationContext.xml中的代码

<?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">

    <bean id="driverManagerDateSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql:///gjp"/>
        <property name="username" value="root"/>
        <property name="password" value="root"/>
    </bean>

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="driverManagerDataSource"/>
    </bean>
</beans> 

java中的代码

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class Test01 {
    
    

    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Test
    public void test1() {

        // 使用JdbcTemplate来完成操作
        jdbcTemplate.execute("update  gjp_zhangwu set money=2330 where zwid=4");// execute方法可以执行任意sql

    }
}

报错的bug是

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jdbcTemplate' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'driverManagerDataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'driverManagerDataSource' is defined

后来我找了半天都没找到…实在没办法,我就改了bean的id我勒个擦..成功了…

<!--bug-->

<bean id="driverManagerDateSource"> 

<!--我见过最无语的bug,修改id的值即可...-->
