在我的控制器中有不同的方法我想用一个表单动作来调用它们。我不知道如何将请求映射到具有不同提交按钮值的特定方法，当我运行我的索引页面时，它直接从它们转到控制器它可以从view()我的控制器呈现视图，并且在Search .jsp打开时我得到了我的输入字段上的默认0值EmployeeId我不知道它为什么会发生请帮助我春天的新人

这是我的控制器

   package com.nousinfo.tutorial.controllers;

import java.util.List;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import com.nousinfo.tutorial.model.EmployeeForm;
import com.nousinfo.tutorial.service.impl.EmployeeServiceImpl;
import com.nousinfo.tutorial.service.model.EmployeeBO;

@Controller
@RequestMapping("/search")
public class SearchEmployeeController {

    private EmployeeServiceImpl employeeServiceImpl;

    public void setEmployeeServiceImpl(EmployeeServiceImpl employeeServiceImpl) {
        this.employeeServiceImpl = employeeServiceImpl;
    }



    @RequestMapping(value = "/searchspring", method = RequestMethod.GET)
    public ModelAndView view(
            @ModelAttribute("employeeForm") EmployeeForm employeeForm)
            throws Exception {
        ModelAndView model = new ModelAndView();
        model.addObject("employeeForm", employeeForm);
        model.setViewName("Search");

        return model;
    }

    @RequestMapping(value = "/employeeNo", method = RequestMethod.POST)
    public ModelAndView searchByEmpNo(
            @ModelAttribute("employeeForm") EmployeeForm employeeForm)
            throws Exception {
        ModelAndView model = new ModelAndView();
        model.addObject("employeeForm", employeeForm);
        Long i = employeeForm.getEmployeeNumber();

        EmployeeBO employeeBO = employeeServiceImpl.getEmployee(i);
        System.out.println(employeeBO);
        model.addObject("employeeBO", employeeBO);

        model.setViewName("EmployeeDetail");
        return model;
    }

    @RequestMapping(value = "/empByName", method = RequestMethod.POST)
    public ModelAndView searchByEmployeeName(
            @ModelAttribute("employeeForm") EmployeeForm employeeForm) {
        ModelAndView model = new ModelAndView();
        model.addObject("employeeForm", employeeForm);
        List<EmployeeBO> employeeBOs = employeeServiceImpl
                .findEmployees(employeeForm.getFirstName());
        model.addObject("listEmployeeBO", employeeBOs);
        model.setViewName("EmployeeList");
        return model;

    }

    @RequestMapping(value = "/empByDeptId", method = RequestMethod.POST)
    public ModelAndView searchByDeptId(
            @ModelAttribute("employeeForm") EmployeeForm employeeForm) {
        ModelAndView model = new ModelAndView();
        model.addObject("employeeForm", employeeForm);
        List<EmployeeBO> employeeBOs = employeeServiceImpl
                .getAllEmployeeByDeptid(employeeForm.getDepartmentId());
        model.addObject("listEmployeeBO", employeeBOs);
        model.setViewName("EmployeeList");

        return model;

    }

}

这是我的 index.jsp

    <%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

<%  
response.sendRedirect("/EmployeeWebSpring/search/searchspring");
%>

这是我的 search.jsp

作为基于单击的按钮为同一表单配置不同端点的替代方法（使用 HTML 中的单独表单或通过 JS 更改表单操作），您可以使用注释的params属性RequestMapping将表单提交进一步缩小到特定的控制器方法基于按钮的值（或任何其他表单提交字段）。有关更多详细信息，请参阅Spring 文档。

使用此策略，您的请求映射将如下所示：

@RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindByName")
public ModelAndView searchByEmployeeName(
        @ModelAttribute("employeeForm") EmployeeForm employeeForm) {
...

@RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindByDeptNO")
public ModelAndView searchByDeptId(
        @ModelAttribute("employeeForm") EmployeeForm employeeForm) {
...

@RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindById")
public ModelAndView searchByEmpNo(
        @ModelAttribute("employeeForm") EmployeeForm employeeForm)
        throws Exception {
...

我不知道如何将请求映射到具有不同提交按钮值的特定方法

以单独的形式进行每个搜索。每个表单映射到不同的控制器方法。像这样：

<form:form action="empById" method="post" commandName="searchBean">
    Employee_ID
    <form:input path="employeeNumber"  />
    <input type="submit" name="method" value="FindById" />
</form:form>
<form:form action="empByName" method="post" commandName="searchBean">
    Employee_Name
    <form:input path="firstName" />
    <input type="submit" name="method" value="FindByName" />
</form:form>
<form:form action="empByDeptNo" method="post" commandName="searchBean">
    Employee_Name
    <form:input path="departmentId" />
    <input type="submit" name="method" value="FindByDeptNO" />
</form:form>

现在不同的搜索请求将映射到正确的控制器方法。

我的 EmployeeId 输入字段默认值为 0 我不知道为什么会发生

在将 EmployeeForm 的实例添加到模型之前，请将其初始化为您希望在搜索页面中看到的默认值。
