Spring用@Autowired注入Map类型Bean时报错解决

异常如下

nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [java.lang.String] found for dependency [map with value type java.lang.String]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

代码如下：

    @Autowired    private Map<String, String> testMap;

配置如下：

    <util:map id="testMap">        <entry key="101" value="foo" />    </util:map>

原因如下：
注入Map类型的bean时，由于@Autowired按类型注入的，找不到对应Key中String类型的Bean，所有报错，用@Resource替代即可。

解决：

@Resourceprivate Map<String, String> testMap;
