网上搜了下说是：
1。必须在实现类中以@Service或@Component注解才行。 
2。自动写入的时候把接口写成实现类了也会出现异常 。（但是我检查代码并没有出现这类情况） 
请各位帮忙指点  谢谢`~

Answer 1

menuServiceImple
看看你注入的名字和这个一样吗 不一样肯定会报错的啊

Answer 2

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory检查你的配置文件，和发下你的配置文件。

Answer 3

spring_Dao.xml配置文件中tMenuDAO虽然配置了，但是找不到set/get方法或set/get方法不对你看看tMenuDAO这个是在哪里进行注入的，是哪一个类的属性？

Answer 4

另外：检查sessionFactory
Does the parameter type of the setter match the return type of the getter?

Answer 5

任何组件都必须用注解，加入到Ioc窗口中，就如同你在xml中写一个<bean>标签一样你的Dao都没有加入容器，请问在service直接用，spring知道从那里给你偷一个过来？？

Answer 7

org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory' of bean class [com.cxsoft.dao.TMenuDAO]: Bean property 'sessionFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?这个是重点...

Answer 8

'sessionFactory' is not writable or has an invalid setter method

Answer 9

在menuServiceImple下面的属性sessionFactory上加注解    @Autowired。或者是加一个setter方法

Answer 10

spring_Dao.xml配置文件中tMenuDAO虽然配置了，但是找不到set/get方法或set/get方法不对你看看tMenuDAO这个是在哪里进行注入的，是哪一个类的属性？ 

Answer 11

错误提示很明显，检查下DAO中对sessionFactory这个属性注入时要用到的set方法有没有
