上下文.xml

    <Context antiJARLocking="true" path="/SpringMVCTest">
     <Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" 
            maxActive="20" maxIdle="10" maxWait="10000" 
            name="jdbc/pluto" password="" 
            type="javax.sql.DataSource" 
            url="jdbc:mysql://localhost:3306/spring?zeroDateTimeBehavior=convertToNull" 
            username="pluto"/>
</Context>

in spring-servlet config bean is:

在 spring-servlet 配置 bean 中是：

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
            <property name="jdbc/pluto" value="java:comp/env/jdbc/pluto"/>
        </bean>

i am getting this error

我收到这个错误

You have a bean definition as such

你有一个 bean 定义

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jdbc/pluto" value="java:comp/env/jdbc/pluto"/>
</bean>

The property name jdbc/plutois supposed to match a setter, so Spring expects something like setJdbc/Pluto()but that is obviously not correct java syntax.

属性名称jdbc/pluto应该与 setter 匹配，因此 Spring 需要类似的东西，setJdbc/Pluto()但这显然不是正确的 java 语法。

Looking at the JndiObjectFactoryBeanit looks like you want the setJndiName()method from JndiObjectLocatorsuper class.

看着JndiObjectFactoryBean看起来你想要setJndiName()来自JndiObjectLocator超类的方法。

So your bean should look like

所以你的豆子应该看起来像

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/pluto"/>
</bean>
