springboot项目小总结
使用模板引擎 thyemlef 可以直接将 html文件进行导入
loginhtml文件 html中常用的表达式
<link href="asserts/css/signin.css" th:href="@{/asserts/css/signin.css}" rel="stylesheet">
<form class="form-signin" action="dashboard.html" th:action="@{/user/login}" method="post">
<img class="mb-4" src="asserts/img/bootstrap-solid.svg" th:src="@{asserts/img/bootstrap-solid.svg}" alt="" width="72" height="72">
<h1 class="h3 mb-3 font-weight-normal" th:text="#{login.tip}">Please sign in</h1>
<p style="color: red" th:text="${msg}" th:if="${not #strings.isEmpty(msg)}"></p>
<input type="password" name="password" class="form-control" th:placeholder="#{login.password}" placeholder="Password" required="">
<a class="btn btn-sm" th:href="@{/index.html(l='zh_CN')}">中文</a>
<a class="btn btn-sm" th:href="@{/index.html(l='en_US')}">English</a>
参数直接写在（）中
<input type="checkbox" value="remember-me"/> [[#{login.remember}]] 行内表达式

又因为html中页面中会有很多重复的代码此时可以抽取出来常用的操作有
可以将抽取的代码放在一个文件夹中
<!--引入上边栏目-->
<!--引入topbar-->
<div th:replace="commons/bar::topbar"></div>
<!--引入sidebar-->
<div th:replace="commons/bar::#sidebar(activeUri='main.html')"></div>

自定义拦截器
LoginHandlerIntercepter
package cn.edu.aynu.springboot.zhaoyujing.Component; import org.springframework.web.servlet.HandlerInterceptor; import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse; public class LoginHandlerInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
String user = (String) request.getSession().getAttribute("loginUser");
if (user==null){
/*未登录，返回登录页*/
request.setAttribute("msg","没有权限，请先登录");
request.getRequestDispatcher("/").forward(request,response);
return false;
}else{
/*登录成功*/
return true;
} }
}
MyErrorAttributes (不过我好想没有成功页面并没有显示自定义的异常信息)
package cn.edu.aynu.springboot.zhaoyujing.Component; import org.springframework.boot.web.servlet.error.DefaultErrorAttributes;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.WebRequest; import java.util.Map; //给容器中加入我们自己定义的ErrorAttributes
@Component
public class MyErrorAttributes extends DefaultErrorAttributes {
@Override
public Map<String, Object> getErrorAttributes(WebRequest webRequest, boolean includeStackTrace) {
Map<String, Object> map = super.getErrorAttributes(webRequest, includeStackTrace);
map.put("company","atguigu");
//我们的异常处理器携带的数据
Map<String,Object> ext = (Map<String, Object>) webRequest.getAttribute("ext", );
map.put("ext",ext);
return map; }
/*//返回值的map就是页面和json能获取的所有字段
@Override
public Map<String, Object> getErrorAttributes(RequestAttributes requestAttributes, boolean includeStackTrace) {
Map<String, Object> map = super.getErrorAttributes(requestAttributes, includeStackTrace);
map.put("company","atguigu"); //我们的异常处理器携带的数据
Map<String,Object> ext = (Map<String, Object>) requestAttributes.getAttribute("ext", 0);
map.put("ext",ext);
return map;
