先看一个简单的项目架构:
在架构方面唯一需要说的是采用的是spring的注解:
下面是部分代码,部分。
/** * @author jessonlv * 用户注册接口 */ <strong>@Controller @RequestMapping("/user")</strong> public class UserInfoController { @Autowired private UserInfoManager userManager; //接口文档 <strong>@RequestMapping(method=RequestMethod.GET)</strong> public String list(HttpServletRequest request,HttpServletResponse response){ response.setContentType("text/html;charset=utf-8"); return "user"; } //检测用户信息-根据帐户 <strong>@RequestMapping(value="/check",method=RequestMethod.GET) </strong> public String getUser(HttpServletRequest request,HttpServletResponse response) throws Exception{ //设置HTTP头 response.setContentType("text/html;charset=utf-8"); //参数获取 String account=StringUtil.formatStringParameter(request.getParameter("account"), null); String key=StringUtil.formatStringParameter(request.getParameter("key"), null);//验证调用方 //参数有效性验证 if(account==null){ throw new ParameterException(); } //TODO:key验证 //查询对象 BasicDBObject o=new BasicDBObject("account",account); try { //取数据库 DBObject doc=userManager.getUserInfo(o); //输出结果 PrintWriter writer=response.getWriter(); writer.write(doc.toString()); } catch (Exception e) { e.printStackTrace(); //输出结果 PrintWriter writer=response.getWriter(); writer.write(new BasicDBObject().toString()); } //db.find(query).skip(pos).limit(pagesize)分页 return null; }粗体部分就是spring的注解。我们得到的接口调用是这个样子的:http://localhost/ucenter/user/check?account=11&pwd=11111 注意是get请求。
采用mongodb的最大好处中的其中一个就是不用写bean,只需做一些简单的配置
我们看spring-servlet.xml 的配置内容
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:util="http://www.springframework.org/schema/util" xmlns:p="http://www.springframework.org/schema/p" xmlns:cache="http://www.springframework.org/schema/cache" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tool="http://www.springframework.org/schema/tool" xsi:schemaLocation=" http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd http://www.springframework.org/schema/tool http://www.springframework.org/schema/tool/spring-tool-3.1.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd" default-autowire="byName" default-lazy-init="true"> <context:annotation-config /> <context:component-scan base-package="com.ishowchina.user" /> <!-- 启动Spring MVC的注解功能,完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".html" /> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" p:defaultEncoding="utf-8" /> <!-- 支持json --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean> </list> </property> </bean> <!-- 导入配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>classpath:appconfig.properties</value> </list> </property> </bean> <!-- 数据源 --> <bean id="dataSource" class="com.ishowchina.user.dao.DataSource"> <property name="ip" value="localhost"/> <property name="port" value="27017"/> </bean> <bean id="userDao" class="com.ishowchina.user.dao.impl.UserInfoDaoImpl"> <property name="dbName" value="prop"/> <property name="tableName" value="userinfo"/> <property name="dataSource" ref="dataSource"/> </bean> <bean id="stationDao" class="com.ishowchina.user.dao.impl.StationInfoDaoImpl"> <property name="dbName" value="prop"/> <property name="tableName" value="stationinfo"/> <property name="dataSource" ref="dataSource"/> </bean> </beans>
上面的都是些常规的配置,最重要的就是数据源部分
道理其实还是和bean是一样的,这在项目启动的前期都已经映射了。每写一个dao就配置一个
接口的输出结果也很简单:DBObject myDocDbObject = userManager.getUserInfo(repeatAccount);
String str = myDocDbObject.toString(); 是一个json格式的字符。
呵呵,做个小总结,方便忘记了。

How to effectively monitor MySQL performance? Use tools such as mysqladmin, SHOWGLOBALSTATUS, PerconaMonitoring and Management (PMM), and MySQL EnterpriseMonitor. 1. Use mysqladmin to view the number of connections. 2. Use SHOWGLOBALSTATUS to view the query number. 3.PMM provides detailed performance data and graphical interface. 4.MySQLEnterpriseMonitor provides rich monitoring functions and alarm mechanisms.

The difference between MySQL and SQLServer is: 1) MySQL is open source and suitable for web and embedded systems, 2) SQLServer is a commercial product of Microsoft and is suitable for enterprise-level applications. There are significant differences between the two in storage engine, performance optimization and application scenarios. When choosing, you need to consider project size and future scalability.

In enterprise-level application scenarios that require high availability, advanced security and good integration, SQLServer should be chosen instead of MySQL. 1) SQLServer provides enterprise-level features such as high availability and advanced security. 2) It is closely integrated with Microsoft ecosystems such as VisualStudio and PowerBI. 3) SQLServer performs excellent in performance optimization and supports memory-optimized tables and column storage indexes.

A MySQL trigger is an automatically executed stored procedure associated with a table that is used to perform a series of operations when a specific data operation is performed. 1) Trigger definition and function: used for data verification, logging, etc. 2) Working principle: It is divided into BEFORE and AFTER, and supports row-level triggering. 3) Example of use: Can be used to record salary changes or update inventory. 4) Debugging skills: Use SHOWTRIGGERS and SHOWCREATETRIGGER commands. 5) Performance optimization: Avoid complex operations, use indexes, and manage transactions.

The steps to create and manage user accounts in MySQL are as follows: 1. Create a user: Use CREATEUSER'newuser'@'localhost'IDENTIFIEDBY'password'; 2. Assign permissions: Use GRANTSELECT, INSERT, UPDATEONmydatabase.TO'newuser'@'localhost'; 3. Fix permission error: Use REVOKEALLPRIVILEGESONmydatabase.FROM'newuser'@'localhost'; then reassign permissions; 4. Optimization permissions: Use SHOWGRA

MySQL is suitable for rapid development and small and medium-sized applications, while Oracle is suitable for large enterprises and high availability needs. 1) MySQL is open source and easy to use, suitable for web applications and small and medium-sized enterprises. 2) Oracle is powerful and suitable for large enterprises and government agencies. 3) MySQL supports a variety of storage engines, and Oracle provides rich enterprise-level functions.

The disadvantages of MySQL compared to other relational databases include: 1. Performance issues: You may encounter bottlenecks when processing large-scale data, and PostgreSQL performs better in complex queries and big data processing. 2. Scalability: The horizontal scaling ability is not as good as Google Spanner and Amazon Aurora. 3. Functional limitations: Not as good as PostgreSQL and Oracle in advanced functions, some functions require more custom code and maintenance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
