Action代码:

@Controller
@Scope("prototype")
@ParentPackage("struts-default")
@Namespace("/riskConfig")
public class RiskConfigAction extends BaseAction implements ModelDriven<Map> {

    private RiskConfigService riskConfigService;

    Map map = new HashMap();

    @Override
    public Map getModel() {
        return map;
    }

    @Action(value = "getRegionList", results = {
            @Result(name = "success", location = "/jsp/riskConfig/region.jsp", type = "dispatcher") })
    public String getRegionList() {
        List<Map<String, Object>> regionList = riskConfigService.getRegion();
        request.setAttribute("regionList", regionList);
        return "success";
    }

}

基本上还是Struts的配置文件的问题,修改后的配置文件如下:

修改了两行配置代码,基本上解决了当前问题,以及访问service自动注入失败导致的访问Action报空指针异常的问题

没有找到你的userService,看看你命名空间是否正确的,还有UserServiceImpl的注解写正确没有

ssm框架新版本使用报错
我用的win10+MyEclipse2016+jdk1.8+spring4.2.4+MyBatis3.3的ssm框架的web应用总是在访问action时报错 ``` HTTP Status 500 - Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user 'root'@'localhost' (using password: YES)) ``` ,但是在低版本的jdk和lib下项目没有任何问题,换成新版本就出错了,找了好长时间没有找到答案,大家有没有遇到过,或者可以用的ssm高版本的lib分享一下

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?

程序员接私活怎样防止做完了不给钱?
