NotWritablePropertyException-初始化上下文时-Spring

Question

这在春季社区是一个很普遍的问题。 但是，即使参考了许多建议和答案，我也无法使下面的程序正常工作。

我需要在Spring bean中注入String类型的属性。

这是bean的定义：

<bean id="AzoneMessageTransformer" class="com.test.wsg.RequestMessageTransformer">      
    <property name="converAndMarshal" value="false" />
</bean>

<bean id="BzoneMessageTransformer" class="com.test.wsg.RequestMessageTransformer">
    <property name="converAndMarshal" value="false" />
    <property name="authCode" >
        <value>BZ</value>
    </property>
</bean>

这是Spring bean：

public class RequestMessageTransformer implements InitializingBean {

    private String authCode = null;

    private boolean converAndMarshal = true;

    public void setConverAndMarshal(boolean converAndMarshal) {
        this.converAndMarshal = converAndMarshal;
    }

    public boolean isConverAndMarshal() {
        return converAndMarshal;
    }

    public void setAuthCode(String authCode) {
        this.authCode = authCode;
    }

    public String getAuthCode() {
        return authCode;
    }

    }

初始化上下文时收到以下错误：

        at java.lang.Thread.run(Thread.java:744)
Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'authCode' of bean class [com.test.wsg.RequestMessageTransformer]: Bean property 'authCode' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

        at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1502)

非常感谢您指出我的错误的任何帮助和建议。

提前致谢！

authCode是字符串属性，应设置类似以下属性

<bean id="BzoneMessageTransformer" class="com.test.wsg.RequestMessageTransformer">
    <property name="converAndMarshal" value="false" />
    <property name="authCode" value="BZ" />        

</bean>
