Question

在我的应用程序中已经配置了多个数据源，因此需要以不同的名称创建jdbcTemplate。我在更改jdbcTemplate名称时遇到异常

的applicationContext.xml

<bean id="reportsViewTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="ds"></property>
</bean>

<bean id="edao" class="com.myapp.dao.EmployeeDao">
    <property name="jdbcTemplate1" ref="reportsViewTemplate"></property>
</bean>

在我的DAO中

private JdbcTemplate jdbcTemplate1;

public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
    this.jdbcTemplate1 = jdbcTemplate;
}

在尝试更改名称时获得以下异常

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'edao' defined in class path resource [ApplicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'jdbcTemplate1' of bean class [com.myapp.dao.EmployeeDao]: Bean property 'jdbcTemplate1' is not writable or has an invalid setter method. Did you mean 'jdbcTemplate'?

我想将名称从jdbcTemplate更改为任何其他名称。如何实现？

Answer 1

在所有地方看起来你已经将jdbcTemplate属性名改为jdbcTemplate 1。请重新检查或共享已更改的xml和java文件。

如何更改JdbcTemplate名称？
