Java Web 后台controller中的方法返回一个jsp页面后。。。。。

Java项目jsp页面使用window.location="url路径“跳转后,经过后台controller中的方法返回一个新的jsp页面,但是新页面不立即加载,而是把同样的URL请求不断地重复发向后台同样的方法中很多次后才加载,而且页面内容(一个表格)重复加载,导致前台页面卡死(因为加载了很多同样的表格,查看页面源代码是一个body里面加载了很多table,而我的jsp页面就一个table的代码,页面过长滚动条的滑块都变得很小,卡的拉不动),请问是什么原因。我用的是chrome浏览器,换成Firefox后就不会出现这种情况。
在图片中的代码第9行断点调试时,按F8后页面没加,此时同样的请求再次进入方法,9行断点再次触发,如此十几次,页面倒是出现了,但是重复加载了很多。

SSM框架中,怎么通过controller实现页面的跳转?
今天接触SSM框架的第四天,后台Mybatis生成dao、entity和mapper后,测试成功,能够正常读写数据库了,但是,在加入页面之后,通过controller不能实现页面的跳转,特求助~~ 访问情况: ![图片说明](https://img-ask.csdn.net/upload/201811/27/1543304296_872148.png) 点击跳转后, ![图片说明](https://img-ask.csdn.net/upload/201811/27/1543304328_484707.png) 出现404的错误,个人认为,可能是没有找到controller 代码: messageController.java ``` @Controller public class messageController { @RequestMapping("/message/go") public String gotest(){ return "second"; } } ``` index.jsp ``` <%@page contentType="text/html; charset=UTF-8" language="java" %> <html> <head> <title>首页</title> </head> <body> <h2>Hello World!</h2> <a href="/message/go">点击跳转</a> <p id="test">Hello World!</p> <button type="button" onclick="selectUser()">onclick test</button> </body> </html> ``` reach.jsp ``` <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>跳到这里了</title> </head> <body> 跳转成功!!!

SpringBoot前端能不能遍历后台传过来的参数
``` 3.在templates中添加html的页面: index.html: <!DOCTYPE html> <html lang="en" xmlns:th="http://www.w3.org/1999/xhtml"> <head> <meta charset="UTF-8"> <title>第一个HTML页面</title> </head> <body> <h1>Hello Spring Boot!!!</h1> <p th:text="${hello}"></p> <div> <p th:text="${say}"></p> </div> </body> </html> 4.编写controller层 HelloController: import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import java.util.HashMap; @Controller //注意这里必须为Controller public class HelloController { /** * 本地访问内容地址 :http://localhost:8080/hello * @param map * @return */ @RequestMapping("/hello") public String helloHtml(HashMap<String, Object> map, Model model) { model.addAttribute("say","欢迎欢迎,热烈欢迎"); map.put("hello", "欢迎进入HTML页面"); return "index"; } } 找了一段示例代码,这些代码,都只能在前端一个一个取参数的值,这样做不灵活, 能不能遍历呢, 以前Jsp的时候,我们是比较方便的,遍历了参数,转成Json格式,前台很方便用值的,就不用每次都自己把参数一个一个写出来,麻烦,通用性也不够 有会的吗? ```

SpringMVC与jsp传值跳转
新人在做东西,最新想做一个跳转 a.jsp有按钮,按下之后会将json格式的参数值发送给后台的controller,然后controller经过处理会将这些json数据发送给b.jsp,b接收解析后展示出来 现在有几个问题在这里想让大家帮忙解答一下: 首先是a.jsp怎么发送数据给controller?我原先一直在使用jquery的ajax发送数据,但是这个样子无法实现跳转功能,并且a.jsp处于web-inf中并且是动态生成的,所以就被难住了 第二个问题是controller怎么再把数据发出去?我现在是使用ModelAndView,但是现在不能跳转我也不知道是否发送成功了 第三个问题是b.jsp怎么接受?我现在的想法是var a="${requestScope.message}" 但是不知道能不能成功,想让大家帮忙解决一下。先谢谢了

return "succ"; }*/ } 4:UsernamePasswordToken 我没有这个类,这好像是一个方法-------网上好像说这是个认证机制,,不知道跳转不了跟这个有没有关系 网上解释:是最常见的用户名/密码的认证机制;同时,由于它实现了RememberMeAuthenticationToken接口,我们可以通过令牌设置“记住我”的功能。 但是,“已记住”和“已认证”是有区别的: 已记住的用户仅仅是非匿名用户,你可以通过subject.getPrincipals()获取用户信息。但是它并非是认证通过的用户,当你访问需要认证用户的功能时,你仍然需要重新提交认证信息。 这一区别可以参考淘宝网站,网站会默认记住登录的用户,再次访问网站时,对于非敏感的页面功能,页面上会显示记住的用户信息,但是当你访问网站账户信息时仍然需要再次进行登录认证。 5: 我的自定义数据库配置“jdbc.properties”: driverClassName=com.mysql.jdbc.Driver validationQuery=SELECT 1 jdbc_url=jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&useSSL=false jdbc_username=root jdbc_password=1234 6:"generatorConfig.xml" 这个就是上面的数据库驱动的配置 <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" > <generatorConfiguration> <!--classPathEntry:数据库的JDBC驱动 --> <!-- location="D:\Develop\MvnRepo\mysql\mysql-connector-java\5.1.34\mysql-connector-java-5.1.34.jar"/> --> <classPathEntry location="D:\Users\lydia\workspaceSSH\shopCMS\src\main\webapp\WEB-INF\lib\mysql-connector-java-5.1.34.jar"/> <context id="MysqlTables" targetRuntime="MyBatis3"> <!-- 注意这里面的顺序确定的,不能随变更改 --> <!-- 自定义的分页插件 <plugin type="com.deppon.foss.module.helloworld.shared.PaginationPlugin"/> --> <!-- 可选的(0 or 1) --> <!-- 注释生成器 --> <commentGenerator> <!-- 是否去除自动生成的注释 true:是 : false:否 --> <property name="suppressAllComments" value="true"/> </commentGenerator> <!-- 必须的(1 required) --> <!--数据库连接的信息:驱动类、连接地址、用户名、密码 connectionURL="jdbc:mysql://localhost:3306/work_attendance" --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/shop" userId="root" password="1234"> </jdbcConnection> <!-- 可选的(0 or 1) --> <!-- 类型转换器或者加类型解析器 --> <!-- 默认false,把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer true,把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal --> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!-- 必须的(1 required) --> <!-- java模型生成器 --> <!-- targetProject:自动生成代码的位置 --> <javaModelGenerator targetPackage="com.coder520.user.entity" targetProject="D:\Develop\IDEAWorkPlace\work-attendance\src\main\java" > <!--TODO enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="true"/> <!-- 从数据库返回的值被清理前后的空格 --> <property name="trimStrings" value="true"/> </javaModelGenerator> <!-- 必须的(1 required) --> <!-- map xml 生成器 <sqlMapGenerator targetPackage="com.coder520.user.dao" targetProject="D:\Develop\IDEAWorkPlace\work-attendance\src\main\java"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> --> <sqlMapGenerator targetPackage="com.coder520.user.dao" targetProject="D:\Users\lydia\workspaceSSH\shopCMS\src\main\java"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!-- 可选的(0 or 1) --> <!-- mapper 或者就是dao接口生成器 --> <javaClientGenerator targetPackage="com.coder520.user.dao" targetProject="D:\Users\lydia\workspaceSSH\shopCMS\src\main\java" type="XMLMAPPER"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!-- 必须的(1...N) --> <!-- pojo 实体生成器 --> <!-- tableName:用于自动生成代码的数据库表;domainObjectName:对应于数据库表的javaBean类名 --> <!-- schema即为数据库名 可不写 --> <table tableName="role" domainObjectName="Role" enableInsert="true" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> <!-- 忽略字段 可选的(0 or 1) --> <!-- <ignoreColumn column="is_use" /> --> <!--//无论字段是什么类型,生成的类属性都是varchar。 可选的(0 or 1) 测试无效 --> <!-- <columnOverride column="city_code" jdbcType="VARCHAR" /> --> </table> <table tableName="permission" domainObjectName="Permission" enableInsert="true" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"> <!-- 忽略字段 可选的(0 or 1) --> <!-- <ignoreColumn column="is_use" /> --> <!--//无论字段是什么类型,生成的类属性都是varchar。 可选的(0 or 1) 测试无效 --> <!-- <columnOverride column="city_code" jdbcType="VARCHAR" /> --> </table> </context> </generatorConfiguration> 万分感谢大佬,,,,,帮我解决这问题我就认你当师傅,,,大佬 ,,拜托了,,,还需要什么麻烦留下言哈

jquerymobile写的一个登陆页面问题
用jquerymobile写了一个登陆页面,后台是spring3+mybatis,主要的思路是异步提交验证,如果验证失败,直接在页面上提示错误信息,验证成功则通过changePage刷新页面。 遇到的问题是: 1、在spring的controller中返回这个页面后,登录页面虽然展现出来了,但是$(document).ready(function() {...})没有起作用,手工强制刷新页面可以起作用; 2、Ajax的POST方式没有起作用,点击按钮总是GET方式。。。 页面代码如下,请各位大侠帮看下,真心感谢! <%@ page language="java" pageEncoding="UTF-8" %> <%@ include file="/WEB-INF/views/include/taglibs.jsp" %> <!DOCTYPE html> <html> <head> <title>login</title> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.css" /> <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script> <script type="text/javascript"> function onSuccess(data, status) { data = $.parseJSON(data) //data = $.trim(data); if(data.flag == "Y") { //成功,进入新页面 $.mobile.changePage(data.url); } else { $("#message").css("color", "#ff0000"); $("#message").text(data.msg); } } $(document).ready(function() { alert("ready"); $("#btnLogin").click(function(e){ var formData = $("#frmLogin").serialize(); alert(formData); $.ajax({ type: "POST", url: "${ctx}/login", cache: false, data: formData, success: onSuccess }); e.preventDefault(); }); }); </script> <script src="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"></script> </head> <body> <div id="message"></div> <form id="frmLogin"> <label for="memberId">会员ID:</label> <input name="memberId" id="memberId" data-mini="true" data-clear-btn="true" type="text" autofocus required> <label for="password">密码:</label> <input name="password" id="password" data-mini="true" type="password" autofocus required> <br/> <div align="center"> <input value="提交验证" id="btnLogin" type=submit data-inline="true" data-mini="true" data-icon="check" data-theme="b"> <!-- <input value="重 填" type="reset" data-inline="true" data-mini="true" data-icon="delete" data-theme="b"> --> </div> </form> </body> </html>

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
