Question

我试图通过spring将数据保存到表中，但是这个错误会在数据提交时显示..

org.springframework.beans.NotReadablePropertyException：bean类的无效属性'user'[com.jit.model.Signup]：Bean属性'user'不可读或getter方法无效：是否返回getter的类型与setter的参数类型匹配？

控制器类

  @Controller
public class DatabaseController 
{
       @RequestMapping("/signup.htm")
       public String loginCheck(@ModelAttribute("bean") @Valid Signup bean,BindingResult result,HttpServletRequest request , HttpServletResponse response) throws IOException {

           Session session= HiberSession.getHiber();
           if (result.hasErrors()){
               return "signup";
           } else{
              session.save(bean);      
             return "abc";
           }

Bean类

我要说你应该避免使用hibernate来保留保留字的表名。当然你可以逃脱它，但它可能在将来引起问题（例如在查询中）。所以最安全的方法是用另一种方式命名表格 - 比如users

@Entity
@Table(name="users")
public class Signup {
}

org.springframework.beans.NotReadablePropertyException：无效的属性＆＃39; user＆＃39; bean类[com.jit.model.Signup]：
