org.springframework.beans.NotWritablePropertyException:Bean property 'xxxService' is not writable or has an invalid setter method.

• 完整报错提示信息：Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'blogDetailsService' of bean class [com.blog.action.BlogDetailsAction]: Bean property 'blogDetailsService' is not writable or has an invalid setter method. Did you mean 'blogDetailService'?
• 解决方案：

1. 保证applicationContext.xml中注入的属性名称与com.blog.action.BlogDetailsAction中属性名称相同

　　  1.1 applicationContext.xml:

<bean name="blogDetailsActionBean" class="com.blog.action.BlogDetailsAction">
    <property name="blogDetailsService" ref="blogDetailsServiceImpl" />
</bean>

　　 1.2 BlogDetailsAction.java

BlogDetailsService blogDetailsService;
public BlogDetailsService getBlogDetailsService() {
    return blogDetailsService;
}

public void setBlogDetailService(BlogDetailsService blogDetailsService) {
    this.blogDetailsService = blogDetailsService;
}

　　注：一般来说这样就可以解决问题了，但我这里不知道为什么必须将blogDetailsService全部都改成blogDetailService才可以运行。

　　原因：修改的struts.xml未生效。重开工作空间解决。
