java.lang.IllegalStateException:找不到@PathVariable

标签: java spring spring-mvc servlets request-uri

我目前正在开发一个现有项目(java版本:1.7.0,使用Spring MVC框架版本:3.1.4),我们只在一个URI中找到了这个@RequestMapping(value = "/site/apps/{question}.json", method = RequestMethod.GET) public @ResponseBody ServiceResponse moreUsers( @PathVariable("question") final Question question, @RequestParam(value = "sort", required = false) final String sort, final HttpServletRequest request, final Model model) 问题特定的控制器类,如果你们中的任何人已经遇到过这个错误,我将非常感谢你们是如何修复/解决它的?谢谢!

代码(java控制器类的提取部分):

ERROR Error executing request: /site/apps/52440.json
org.springframework.web.bind.annotation.support.HandlerMethodInvocationException: Failed to invoke handler method [public com.project.infrastructure.service.ServiceResponse com.project.plugins.controllers.SiteAppController.moreUsers(com.project.models.node.Question,java.lang.String,javax.servlet.http.HttpServletRequest,org.springframework.ui.Model)]; nested exception is java.lang.IllegalStateException: **Could not find @PathVariable [question] in @RequestMapping**

错误输出我们的tomcat日志(catalina.out文件):

public class Client{

    @Id
    @Column(columnDefinition = "CHAR(11)")
    private String cpf;

    @ManyToMany(cascade = CascadeType.ALL)
    private List<Address> addresses;
    //get set
}

在你的方法处理程序中尝试使用{question} pathVariable作为int,假设你在Question JavaBean&amp;中有int questionid字段。尝试在方法处理程序中构造Question JavaBean ..

@RequestMapping(value = "/site/apps/{question}.json", method = RequestMethod.GET)
public @ResponseBody ServiceResponse moreUsers(
        @PathVariable("question") Integer question,
        @RequestParam(value = "sort", required = false) final String sort,
        final HttpServletRequest request, final Model model){

Question Q=questionservice.getQuestion(question);

}
