    依赖注入失败?

    检查这个blogDaoImpl实现类的bean配置

    这个只贴错误信息不够用的,还得把配置文件和项目目录结构提出来分析下

    现在你看看!

    @AutowiredpublicBloggetBlogById(Integerid){returnsqlSessionTemplate.selectOne(FIND_BLOG,id);}



    这段代码是干啥的。。。

    回复 @so_co:如果你按照我这么改不可能还报一模一样的错误的,把新的错误贴一下还是报上边的错!回复 @so_co:@Autowired要放在注入的前边不是后边回复 @so_co:改成这样试试:@AutowiredprivateSqlSessionTemplatesqlSessionTemplate;publicBloggetBlogById(Integerid){returnsqlSessionTemplate.selectOne(FIND_BLOG,id);}查询的方法@autowired/*注入*/privateSqlSessionTemplatesqlSessionTemplate;

     privateSqlSessionTemplatesqlSessionTemplate;没有注入。1,要么添加注解;2,要么在配置文件中注入,并添加setter方法

     @Autowired这行应该是下面这行的上面吧?

    privateSqlSessionTemplatesqlSessionTemplate;
     @Autowired
     publicBloggetBlogById(Integerid){
      returnsqlSessionTemplate.selectOne(FIND_BLOG,id);

     }



    你应该是想注入 sqlSessionTemplate吧

    Errorcreatingbeanwithname'blogDaoImpl':Injectionofautowireddependenciesfailed;

    Couldnotautowiremethod:publiccom.s2si.entity.Blogcom.s2si.dao.impl.BlogDaoImpl.getBlogById(java.lang.Integer);nestedexceptionisorg.springframework.beans.factory.NoSuchBeanDefinitionException:Noqualifyingbeanoftype[java.lang.Integer]foundfordependency: 


    重点在这里,如三楼所说,你装个方法参数是int的,就不能有autowired注解
