為什么這樣錯了？
@Autowired
private InjectionDAO injectionDAO;
//@Autowired
public InjectionServiceImpl(InjectionDAO injectionDAO) {
this.injectionDAO = injectionDAO;
}
//@Autowired?
public void setInjectionDAO(InjectionDAO injectionDAO) {
this.injectionDAO = injectionDAO;
}

應該是你的配置文件不對，沒能識別@autowired注解

No default constructor found,你自己寫了一個構造器,
public InjectionServiceImpl(InjectionDAO injectionDAO) {
this.injectionDAO = injectionDAO;
}
并且將注解注釋掉了,java你自己謝了構造器他就不會生成默認的構造器,所以找不到了
