VSCode结合maven配置Java开发环境 这里主要介绍一下pom.xml文件的配置，防止遗忘。{message type="success" content="这里主要是配置了struts2的一个环境作为Demo"/}项目结构由于修改了默认的maven项目目录的存储结构，所以需要同步修改pom.xml文件，防止打包失败。简单说一下项目的结构src顶层主要用户存储开发相关的源文件target是intall生成的文件java是空文件夹，目前没用Net下面存放的java文件resources下面就配置了一个struts.xml文件WebContent用于配置jsp等静态文件pom.xml配置如下<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>Cc.LiSen</groupId> <artifactId>Cc.LiSen</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>Cc.LiSen Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.5.1</version> </dependency> </dependencies> <build> <finalName>Cc.LiSen</finalName> <!--项目相关的所有资源路径列表，例如和项目相关的配置文件、属性文件，这些资源被包含在最终的打包文件里。 --> <resources> <resource> <!--描述了资源的目标路径。该路径相对target/classes目录（例如${project.build.outputDirectory}）。 --> <!--举个例子，如果你想资源在特定的包里(org.apache.maven.messages)，你就必须该元素设置为org/apache/maven/messages。 --> <!--然而，如果你只是想把资源放到源码目录结构里，就不需要该配置。 --> <!--是否使用参数值代替参数名。参数值取自properties元素或者文件里配置的属性，文件在filters元素里列出。 --> <filtering>true</filtering> <!--描述存放资源的目录，该路径相对POM路径 --> <directory>${project.basedir}\src\resources</directory> <!--包含的模式列表 --> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <!--排除的模式列表 如果<include>与<exclude>划定的范围存在冲突，以<exclude>为准 --> <excludes> <exclude>jdbc.properties</exclude> </excludes> </resource> </resources> <!--项目源码目录，当构建项目的时候，构建系统会编译目录里的源码。该路径是相对于pom.xml的相对路径。 --> <sourceDirectory>${basedir}\src\</sourceDirectory> <!--项目脚本源码目录，该目录和源码目录不同， 绝大多数情况下，该目录下的内容会被拷贝到输出目录(因为脚本是被解释的，而不是被编译的)。 --> <scriptSourceDirectory>${basedir}\src\scripts</scriptSourceDirectory> <plugins> <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <!--指定web.xml文件的位置--> <webXml>src\WebContent\WEB-INF\web.xml</webXml> <!--指定jsp等文件所在位置--> <warSourceDirectory>src\WebContent</warSourceDirectory> </configuration> </plugin> </plugins> </build> </project> -

WebApi JSONP的支持 最近遇到一个问题，在js中通过ajax访问webapi，出现了跨域的问题就把ajax的datatype改成jsonp，但是随之而来还有其他问题，就是paraserror = 0解决方法：在NuGet中下载webapi对jsonp的支持在Global中添加GlobalConfiguration.Configuration.AddJsonpFormatter(GlobalConfiguration.Configuration.Formatters.JsonFormtter, "callback");这样服务端就算是配好了！ajax调用示例：$.ajax({ url: "http://localhost:37262/api/door", type: "get", dataType: 'JSONP', jsonp:"callback", success: function (data) { console.log(data); }, });

Asp.NetCore MVC控制器分离 DotNetCore默认创建的项目，控制器是放到Controller文件夹下面，为了实现项目松耦合，我们可以见控制器分离到单独的类库项目中。创建控制器类库如上图，我这里创建了一个名为Cn.Com.DotNetCore.Controllers的类库项目，单独用于存储控制器。修改startup.cs类修改startup.cs类中的ConfigureServices方法，修改如下代码var mall = Assembly.Load(new AssemblyName("Cn.Com.DotNetCore.Controllers")); //类库的程序集名称 services.AddMvc().AddApplicationPart(mall).SetCompatibilityVersion(CompatibilityVersion.Version_2_2); 至此，就实现了控制器的分离。

jsp中文乱码问题 初学JSP，尤其是Tomcat环境，经常会因为中文汉字字符集设置问题导致中文乱码，本文就这一问题提出解决方案，解决中文乱码问题，供各位参考，我采用的方案是统一字符集至UTF-8，同时避免GB2312所带来的中文字符集不够用的隐患，需注意的地方有三点，默认情况下是英文字符集。Tomcat 的 server.xml 文件，设置服务器端口工作方式Servlet 和 JavaBean 对字符串字符集处理的统一JSP页面的字符集统一完成这三点统一，中文想乱码都难，如果使用MySQL的话，数据表也需要做UTF-8统一。修改Tomcat的server.xml文件，该文件位于 tomcat/conf，红色部分为添加部分，也就是当前使用的HTTP端口的连接方式的设置。找到Connector 标签，使 Tomcat 服务器以UTF-8模式进行工作，从底层对乱码进行处理，修改如下：<Connector URIEncoding="utf-8" port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> 运行代码内设置如下：JavaBean 和 Servlet 内需要处理中文的地方之前，或者所有函数最前端加上request.setCharacterEncoding ("UTF-8"); response.setCharacterEncoding ("UTF-8");避免在 JavaBean 和 Servlet 内出现汉字乱码。JSP代码中的 JAVA 字符编码设置，在页面上对乱码进行处理。<%@page contentType="text/html"%> <%@page pageEncoding="UTF-8"%>红色为制定JSP处理字符采用UTF-8编码处理方式。<div class="dp-highlighter nogutter"><div class="bar"></div><ol start="1" class="dp-j"><li class="alt"><span><span><%request.setCharacterEncoding (</span><span class="string">"UTF-8"</span><span>);%> </span></span></li></ol></div>JSP内JAVA代码设定接收参数为UTF-8编码JSP 内 HTML 头的编码设置，页面处理以UTF-8，避免显示乱码。<form action=index.jsp method="post"><h3>Please Input Your Name:</h3> <input type="text" size="30" name="中文名字" value="" > <input type=submit value="提交"> </form>接收代码如下：<% // 通过二进制传递的参数，因为UTF-8的设置，无须转换，直接中文操作，而不会出现乱码。 String temp1 = request.getParameter ("yourname"); …… %>采用get方式略有不同，若只采用以上设定，遇中文参数，因编码不同，会导致部分文字信息丢失，所以在提交前务必进行编码，这里用到两个函数java.net.URLDecoder.decode 和java.net.URLDecoder.encode，分别是编码和解码。<a href=" <%=request.getContextPath()%>/index.jsp?传递的参数名= <%=java.net.URLEncoder.encode (传递的汉字变量,"UTF-8")%>"> <%=超链接热点显示内容%> </a>作为参数传递的中文，由 java.net.URLEncoder.encode函数将要发送的变量解析为16进制数字编码，进行URL传递，接收代码如下：<%String str = request.getParameter ("传递的参数名");%> 由此，获得参数后的 str 内将是正确的中文信息，完全避免了乱码的显示。可用 java.net.URLDecoder.decode 函数例如<% String str1 = java.net.URLDecoder.decode(request.getParameter("传递的参数名"),"UTF-8"); %>

asp.net core视图组件 what试图组件是ASP.NET Core MVC中的新特性，类似于部分视图，但是它更加强大。驶入组件不使用模型绑定，并且仅依赖于调用它时所提供的数据。how创建视图组件类using Microsoft.AspNetCore.Mvc; using System; using System.Collections.Generic; using System.Linq; using System.Threading.Tasks; namespace Web.ViewComponents { [ViewComponent(Name = "TopicRankList")] public class TopicRankList : ViewComponent { public IViewComponentResult Invoke() { return View(); } } } 视图搜索路径视图组件的默认视图名称是Default，这意味着你的视图文件通常名为Default.cshtml，可以在创建视图组件结果或调用View方法时指定其他视图名称。视图组件运行时会在以下路径中搜索视图：Views//Components// Views/Shared/Components//所以根据创建的类，我们需要在Views/Shared/Components/TopicRankList文件夹中创建Default.cshtml文件。@{ ViewData["Title"] = "Default"; } <h1>Default</h1>调用视图@await Component.InvokeAsync("TopicRankList")

ASP.NET Core之NLog使用 添加NLog插件修改NLog配置文件可以通过Nuget安装，NLogConfigure手工添加NLog.Configure文件，如下using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Threading.Tasks; using Microsoft.AspNetCore.Mvc; using Microsoft.Extensions.Logging; using NLog; using Web.Models; namespace Web.Controllers { public class HomeController : Controller { private readonly ILogger<HomeController> _log; public HomeController(ILogger<HomeController> log) => _log = log; static Logger logger = LogManager.GetCurrentClassLogger(); public IActionResult Index() { logger.Info("测试日志乱码"); return View(); } public IActionResult Privacy() { return View(); } [ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)] public IActionResult Error() { return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier }); } } }修改StartUp.cs文件public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { app.UseRequestIP(); loggerFactory.AddNLog(); env.ConfigureNLog("NLog.configure"); app.Use(async (context, next) => { context.Items["IsVerified"] = true; await next.Invoke(); }); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); app.UseDatabaseErrorPage(); } else { app.UseExceptionHandler("/Error"); } app.UseStaticFiles(); //app.UseDirectoryBrowser(); app.UseAuthentication(); app.UseSession(); app.UseMvc(routes => { routes.MapRoute( name:"area", template: "{area:exists}/{controller=Home}/{action=Index}/{id?}" ); routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); }); }使用NLogpublic class HomeController : Controller { private readonly ILogger<HomeController> _log; public HomeController(ILogger<HomeController> log) => _log = log; static Logger logger = LogManager.GetCurrentClassLogger(); public IActionResult Index() { logger.Info("测试日志乱码"); return View(); } }

根据WSDL文件(java Web Service)生成.cs文件 我们添加webService引用，一般是通过 添加服务引用完成的，其实 添加服务引用 在背后为我们生成了代理类。我们手动生成代理类方法：通过java Web Service，生成wsdl文件：1.1 IE地址栏中输入wsdl的url 例如：http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?wsdl1.2 通过IE的 【文件】-->【另存为】-->文件名中输入 UserService55.wsdl， 保存类型： 所有文件(.) ;开始菜单-->Microsoft Visual Studio 2010 -->Visual Studio Tools-->Visual Studio Command Prompt (2010) ;输入wsdl wsdl文件路径(D:\UserService55.wsdl) /out:UserService55.cs,cs文件生成在 Microsoft Visual Studio 10.0\VC\目录中；
