我不是在写setter getter并使用autowire，而是得到以下错误-
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'aS400Statusfacade' defined in class path resource [CXF-Bean.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'aS400StatusDAO' of bean class [com.metlife.mymet.admin.facade.AS400Statusfacade]: Bean property 'aS400StatusDAO' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

我的Spring-conf.xml
<bean id="aS400Statusfacade"
class="com.metlife.mymet.admin.facade.AS400Statusfacade">
<property name="aS400StatusDAO" ref="aS400StatusDAO"></property>
</bean>
我的自动接线课程-
public class AS400Statusfacade {
Logger logger=Logger.getLogger(AS400Statusfacade.class);
@Autowired
AS400StatusDAO aS400StatusDAO=null;
public String getAS400StatusInformation() {
return aS400StatusDAO.getAS400Status();
}
}
我认为您遇到的问题是，没有设置器和显式标记Spring不会知道您要从中获得什么。
尝试删除显式属性元素。
这将允许@Autowired批注尝试解析该值。
为了进一步说明这一点：
spring-conf.xml
<bean id="aS400Statusfacade"
class="com.metlife.mymet.admin.facade.AS400Statusfacade">
<!--
The following property tag is not necessary. Spring's
@Autowired and associated bean post-processor, will introspect
and set the property with an appropriate candidate bean.
Bean property setter, is not required for the post-processor
to access/set the property.
-->
<!--
<property name="aS400StatusDAO" ref="aS400StatusDAO"></property>
-->
</bean>
