本文详细介绍了如何使用Spring MVC实现用户信息的修改和添加功能，包括控制器方法的定义、页面表单的设计，以及如何通过Thymeleaf模板引擎进行条件渲染。

  //修改用户信息显示页面
    @GetMapping("/emp/{id}")
    public String modifyView(@PathVariable Integer id, Model model){
        model.addAttribute("emp",  dao.get(id));
        Collection<Department>  collection = departmentDao.getDepartments();
        model.addAttribute("deparms",collection);
        return "employee/add";
    }


    //修改用户信息
    @PutMapping("/emp")
    public String modifyEmployee(Employee employee) {
        System.out.println("修改用户Controller:"+employee);
        Employee temp = dao.get(employee.getId());
        if(null!=temp){
            temp.setLastName(employee.getLastName());
            temp.setEmail(employee.getEmail());
            temp.setGender(employee.getGender());
            temp.setDepartment(departmentDao.getDepartment(employee.getDepartment().getId()));
            temp.setBirth(employee.getBirth());
        }
        return "redirect:/emps";
    }

修改添加二合一表单

<form th:action="@{/emp}" method="post">
					<input th:type="hidden" th:if="${emp!=null}" name="id" th:value="${emp.id}">
					<input th:type="hidden" th:if="${emp!=null}" name="_method" value="put">
					<div class="form-group">
						<label>LastName</label>
						<input type="text" class="form-control" name="lastName" value="zhangsan" th:value="${emp!=null}?${emp.lastName}">
					</div>
					<div class="form-group">
						<label>Email</label>
						<input type="email" name="email" class="form-control" value="zhangsan@atguigu.com"   th:value="${emp!=null}?${emp.email}">
					</div>
					<div class="form-group">
