 Exception occurred during processing request:

Unable to instantiate Action, customerAction,  defined for 'customer_list' in namespace '/'Error creating bean with name 'customerAction' defined in class path resource [applicationContext.xml]:

Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException:

Invalid property 'customerService' of bean class [cn.xiaou.web.CustomerAction]:

Bean property 'customerService'is not writable or has an invalid setter method.

Does the parameter type of the setter match the return type of the getter?

在CustomerAction属性注入出现错误，注入的变量名与注入的name名字不同

private CustomerService cs;
