这是错误的信息，service注解成功，但是DAO 就是失败，困扰我很久了，希望大家帮我解决下多谢严重: Servlet /test threw load() exception

Answer 3

不是很明白，感觉你是注解和配制混合着用的吧，但是混着用也没有发现你在xml中配制WeatherServiceImpl和WeatherDao的bean……但是错误很明显，WeatherDao没有注入到类WeatherServiceImpl 
1.如果全用注解的话，你可以在WeatherServiceImpl中weatherDao上边再使用@Qualifer注解，把类WeatherDao注入到类WeatherServiceImpl中
2.如果想用在xml中配置bean的方式，建议你再检查一下了……有没有配置bean WeatherServiceImpl ,而且bean WeatherServiceImpl 中有没有配置bean WeatherDao......
另外，多说一句，你的WeatherAction类好像也有同样的问题

Answer 4

注解的问题,和我的结构很相似@Repository     //看看这里
public interface WeatherDao {
    public WeatherDO findByCityname(String cityname);
    public WeatherDO findByCitycode(String citycode);
    public WeatherDO findByPostcode(String postcode);
   }

spring-service.xml   可以看一下这个配置文件， 修改过后的配置文件<?xml version="1.0" encoding="GBK"?>
