Java Spring MVC中的全局异常防御不起作用

我在我的Spring MVC应用程序中添加了下面的全局异常定义，并得到了下面的异常，但我不知道是什么问题，我认为我的Spring安全性中存在问题，但我不确定是否有人可以帮助我

全局异常定义

<!-- global exception mapping -->
<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
    <property name="exceptionMappings">
    <map>
        <entry key="DataAccessException" value="error" />
    </map>
</property>
<property name="defaultErrorView" value="error"/>
</bean>
<!-- end global exception mapping -->

当此操作发生任何异常时，我得到一个异常org.springframework.web.HttpRequestMethodNotSupportedException:Request方法“GET”不受支持

@RequestMapping(value ="/addUser", method = RequestMethod.POST)
public String addUser(@Valid User user, BindingResult result, Model model, @RequestParam("userRole") String role) throws Exception {
    if(result.hasErrors()) {
        return "register";
    }
    String hashPassword = new PasswordHashProcessor().getHashPassword(user.getPassword());
    user.setPassword(hashPassword);
    daoService.addUser(user, role);
    List<UserRole> users = daoService.getNotAdminUsers();
    model.addAttribute("users", users);
    return "users";
}

显示的日志如下所示

此更新解决的问题

@RequestMapping(value ="/addUser", method = RequestMethod.POST)
public String addUser(@ModelAttribute("user") @Valid User user, BindingResult result) {

    if(result.hasErrors()) {
        return "register";
    }
    String hashPassword = new PasswordHashProcessor().getHashPassword(user.getPassword());
    user.setPassword(hashPassword);
    daoService.addUser(user);
    return "redirect:/getUsers";
}
