springMVC的修改等方法

<form action="init1" th:object="${userBean}" method="post">中init1对应的

@RequestMapping(value = "/init1", method = RequestMethod.POST, params = "add")；

@RequestMapping(value = "/init1", method = RequestMethod.POST, params = "back")。

其中的"add"和"back"与下面有关

<div>

<span><input type="submit" name="add" value="注册" />

<input type="submit" name="back" value="后退" /></span>

</div>

th:object="${userBean}"中的userBean变量与model.addAttribute("userBean", result1);中的userBean对应。

List<UserBean> result1 = helloWorldService.searchUsers();对应Service中的

public UserBean searchUser2(UserBean frm) {

UserBean  result=queryDao.executeForObject("User.selectUser2",frm,UserBean.class);

return result;

}

public List<UserBean> searchUsers() {

List<UserBean>  result=queryDao.executeForObjectList("User.selectUsers",null);

return result;

}

//UserBean显示一条，List<UserBean>显示一个列表，selectUser2对应sql文中的

</select>

<select id="selectUser2"

parameterClass="cn.training.bean.UserBean"

resultClass="cn.training.bean.UserBean">

SELECT

userid as userId,

username as userName

FROM

user

WHERE

userid = #userId#

</select>//
