Question

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">   
    <property name="securityManager" ref="securityManager"/>
    <property name="loginUrl" value="/"/>
    <property name="filterChainDefinitionMap" ref="chainFilterBuff" />
</bean> 

<bean id="chainFilterBuff"   class="org.moofie.test.security.FilterChainBean">
    <property name="filterChainDefinitions">
        <value>/test/login=anon</value>
    </property>
</bean>

以上是我的春季配置

private String filterChainDefinitions;
public String getFilterChainDefinitions() {
    return filterChainDefinitions;
}

public void setFilterChainDefinitions(String filterChainDefinitions) {
    this.filterChainDefinitions = filterChainDefinitions;
}

这是我的java代码，它适用于getter和setter，但我想用@autowired annotaion替换getter和setter：

@Autowired
private String filterChainDefinitions;

它会出错：

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

我的代码怎么了？或者我应该使用其他注释？

Answer 1

setter和getter方式正常工作，因为在您的配置XML中，您使用<bean id="filterChainDefinitions" class="java.lang.String"> <constructor-arg value="/test/login=anon"/> </bean>直接调用setter。

@Autowired适用于显式声明的bean。

如果您想使用@Autowired设置filterChainDefinitions，那么您必须首先声明它，如下所示：

Object.entries()

Spring使用Autowired注释会出错
