摘要：創(chuàng)建一個(gè)工程在里面添加依賴(lài)，依賴(lài)不要隨便改我改了出錯(cuò)了好幾次都找不到原因可以輕松的將對(duì)象轉(zhuǎn)換成對(duì)象和文檔同樣也可以將轉(zhuǎn)換成對(duì)象和配置
1.創(chuàng)建一個(gè)web工程
2.在pom里面添加依賴(lài)，依賴(lài)不要隨便改,我改了出錯(cuò)了好幾次都找不到原因

4.配置applicationContext.xml
5.配置springmvc.xml
text/plain;charset=utf-8
text/html;charset=UTF-8
6.配置springSecurity.xml
7.自定義成功處理的攔截器 MyAuthenticationSuccessHandler
public class MyAuthenticationSuccessHandler implements AuthenticationSuccessHandler {
private final static ObjectMapper objectMapper=new ObjectMapper();
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
//這里是可以拿到用戶(hù)對(duì)的登錄名的
String username = request.getParameter("username");
System.out.println(username);
response.setContentType("application/json;charset=utf-8");
String successMessage = objectMapper.writeValueAsString(new JsonData(200, "登陸成功"));
response.getWriter().print(successMessage);
}
}
自定義失敗處理器的攔截器
public class MyAuthenticationFailureHandler implements AuthenticationFailureHandler{
private final static ObjectMapper objectMapper=new ObjectMapper();
@Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException e) throws IOException, ServletException {
//這里是可以拿到用戶(hù)對(duì)的登錄名的
String username = request.getParameter("username");
System.out.println(username);
response.setContentType("application/json;charset=utf-8");
String failureMessage = objectMapper.writeValueAsString(new JsonData(500, "登陸失敗"));
response.getWriter().print(failureMessage);
}
}
自定義的authentication-provider下面的user-service
定義一個(gè)類(lèi),這個(gè)實(shí)現(xiàn)類(lèi)就是用于封裝數(shù)據(jù)庫(kù)里面的用戶(hù)的信息然后返回給springsecurity,它會(huì)比較從
表單穿過(guò)來(lái)的用戶(hù)名和密碼和數(shù)據(jù)庫(kù)查出來(lái)的用戶(hù)名和密碼進(jìn)行比對(duì)，這里寫(xiě)死，以后再加數(shù)據(jù)庫(kù)
public class MyUserDetailService implements UserDetailsService {
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
//UserDetails：封裝用戶(hù)數(shù)據(jù)的接口,這里應(yīng)該是數(shù)據(jù)庫(kù)查詢(xún)出來(lái)的數(shù)據(jù),當(dāng)返回這個(gè)user對(duì)象時(shí),springsecurity會(huì)把輸入的用戶(hù)名和密碼和這個(gè)對(duì)象里面的用戶(hù)名和密碼進(jìn)行比對(duì)
//成功則認(rèn)證通過(guò),失敗則登陸失敗
User user=new User("jojo","123456", AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_USER"));
return user;
}
}
創(chuàng)建這個(gè)目錄結(jié)構(gòu)
示范
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
商品添加頁(yè)面
商品添加頁(yè)面
其它頁(yè)面一樣
index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
首頁(yè)
一下是網(wǎng)站的功能
商品添加
商品修改
商品查詢(xún)
商品刪除
login.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
登錄頁(yè)面
errorPage.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
自定義錯(cuò)誤頁(yè)面
權(quán)限不足,請(qǐng)正確操作
controller
@Controller
public class MainController {
/**
*
* @return登錄頁(yè)面
*/
@RequestMapping("/userLogin")
public String loginPage()
{
return "login";
}
/**
*
* @return登錄頁(yè)面
*/
@RequestMapping("/error")
public String errorPage()
{
return "errorPage";
}
}
@Controller
@RequestMapping("product")
public class ProductController {
/**
* 商品添加
*/
@RequestMapping("index")
public String index()
{
return "index";
}
/**
* 商品添加
*/
@RequestMapping("add")
public String add()
{
return "product/productAdd";
}
/**
* 商品修改
*/
@RequestMapping("update")
public String update()
{
return "product/productUpdate";
}
/**
* 商品列表
*/
@RequestMapping("list")
public String list()
{
return "product/productList";
}
/**
* 商品刪除
*/
@RequestMapping("delete")
public String delete()
{
return "product/productDelete";
}
}
創(chuàng)建一個(gè)返回給前臺(tái)的包裝類(lèi)，用于返回code和message
public class JsonData {
private Integer code;
private String message;
public JsonData() {
}
public JsonData(Integer code, String message) {
this.code = code;
this.message = message;
}
public Integer getCode() {
return code;
}
public void setCode(Integer code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
