Java 为org.springframework.beans.propertyeditors.StringTrimmerEditor实例化bean时出错

下面是我的applicationContext.xml的外观：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:sec="http://www.springframework.org/schema/security"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

。。。。。

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

我得到这个错误：

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

org.springframework.beans.factory.BeanCreationException:错误 正在创建中定义了名为“CustomEditorConfigure”的bean ServletContext资源[/WEB-INF/spring servlet.xml]：初始化 豆荚失败；嵌套异常是 org.springframework.beans.typemischException:转换失败 将“java.util.LinkedHashMap”类型的属性值转换为所需类型 属性“CustomEditor”的“java.util.Map”；嵌套异常是 java.lang.IllegalArgumentException:无法转换类型的值 [org.springframework.beans.propertyeditors.StringTrimmerEditor]到 属性的必需类型[java.lang.Class] “CustomEditor[java.lang.String]”：PropertyEditor 返回[org.springframework.beans.propertyeditors.ClassEditor] 类型值不正确 [org.springframework.beans.propertyeditors.StringTrimmerEditor]

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

缔约国强调如下：

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

指定要通过映射注册的自定义编辑器，使用所需类型的类名作为键，使用关联PropertyEditor的类名作为值

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

因此，您传入类名，而不是bean本身，作为映射中每个条目的值

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

试着替换

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

<entry key="java.lang.String">
    <ref bean="stringTrimmerEditor"/>
</entry>

与

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

与

<bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
   <property name="customEditors">
        <map>
           <entry key="java.lang.String">
                <ref bean="stringTrimmerEditor"/>
            </entry>
        </map>
    </property>
 </bean>

谢谢你的快速回复。在完成您建议的更改后，现在我得到：org.springframework.beans.factory.BeanCreationException:创建名为“org.springframework.context.annotation.InternalAutowiredNotationProcessor”的bean时出错：bean的实例化失败；嵌套异常为org.springframework.beans.beans实例化异常：无法实例化bean类[org.springframework.beans.propertyeditors.StringTrimmerEditor]：未找到默认构造函数；嵌套异常是java.lang.NoSuchMethodException:org.springframework.beans.propertyeditors.StringTrimmerEditor。@Chandan:很抱歉，我以前的建议不起作用。我编辑我的答案是为了提出另一个建议——这对你有用吗？@Chandan：我再次编辑我的答案是为了提出一些有效的建议——我已经测试过了。抱歉没有测试我以前的建议。
