我正在尝试开发一个Spring应用程序来显示表中的员工，并且在选择单选按钮时，过滤的结果应该显示在同一个表中(相同的jsp)。我在下面尝试过，但得到了 NotReadablePropertyException。请帮忙。
EmployeeController.java
@Controller
public class EmployeeController {
/** Service object to handle web request */
@Autowired
protected EmployeeService empService;
/**
* This method will form the list of employees and return the string to be
* used for spring to fetch the appropriate JSP
*
* @param model
* - Spring Model class object
* @return String - to be used to help spring to fetch the appropriate JSP
*/
@RequestMapping(value = "/employees", method = RequestMethod.GET)
public String getEmployees(Model model) {
List<EmployeeDetails> empList = empService.getEmployeeList();
model.addAttribute("employees", empList);
return "employees";
}
/**
*
*/
@RequestMapping(value = "/filteremployees", method = RequestMethod.POST)
public ModelAndView getFilteredData(
@ModelAttribute("salaryFilterBean") SalaryFilterBean salaryFilterBean) {
System.out.println("Inside controller to filter data");
List<EmployeeDetails> filteredEmpList = empService
.getFilteredEmployeeListBySalary(salaryFilterBean
.getFilteremployees());
System.out.println("filtered data of employee ::: "
+ filteredEmpList.get(0).getEmpSalary());
ModelAndView model = new ModelAndView("employees");
model.addObject("employees", filteredEmpList);
model.addObject("salaryFilterBean", new SalaryFilterBean());
return model;
}
}
SalaryFilterBean.java
public class SalaryFilterBean {
private String filteremployees = null;
/**
* @return the filteremployees
*/
public String getFilteremployees() {
return filteremployees;
}
/**
* @param filteremployees
* the filteremployees to set
*/
public void setFilteremployees(String filteremployees) {
this.filteremployees = filteremployees;
}
}

我哪里出错了？
最佳答案
commandName="employees"
您的 commandName 设置为员工，即
model.addObject("employees", filteredEmpList);
这是
List<EmployeeDetails> filteredEmpList
并且您正在尝试绑定(bind)
<form:radiobutton path="filteremployees" value="< 10000"
onclick="submitForm()" /> Salary < 10000
到它
因此无法在 filteredEmpList 上找到 setFilteremployees() 方法
关于java - spring + jsp + hibernate 中的 NotReadablePropertyException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24278197/
