电子商务网站设计的基本流程,望京SOHO网站建设,基层建设论文查询官方网站,产品盘网站建设最近在回顾和总结一些技术#xff0c;想到了把之前比较火的 SSM 框架重新搭建出来#xff0c;作为一个小结#xff0c;同时也希望本文章写出来能对大家有一些帮助和启发#xff0c;因本人水平有限#xff0c;难免可能会有一些不对之处#xff0c;欢迎各位大神拍砖指教想到了把之前比较火的 SSM 框架重新搭建出来作为一个小结同时也希望本文章写出来能对大家有一些帮助和启发因本人水平有限难免可能会有一些不对之处欢迎各位大神拍砖指教共同进步。本文章示例使用 IntelliJ IDEA 来开发JDK 使用 11 版本其余各框架和技术基本上使用了文章撰写当时的最新版本。好的下面直接进入正题。打开 IntelliJ IDEAFile New Project Maven选中“Create from archetype”然后再选中“org.apache.maven.archetypes:maven-archetype-webapp”Next输入项目的“GroupId”、“ArtifactId”和VersionNext指定“Maven home directory”等配置Next修改Project NameFinish打开项目添加一些必要的目录最终项目框架目录图如下修改pom.xml文件指定各依赖和插件的版本等信息UTF-81111115.2.3.RELEASE4.131.18.103.3.12.3.291.1.213.18.0.191.24.0.12.3.32.9.23.92.10.21.3.1.Final2.13.01.7.303.1.03.1.03.8.13.0.0-M43.2.33.0.0-M13.0.0-M1在标签里面管理各依赖的版本号org.springframeworkspring-context${spring.version}org.springframeworkspring-context-support${spring.version}org.springframeworkspring-beans${spring.version}org.springframeworkspring-jdbc${spring.version}org.springframeworkspring-aop${spring.version}org.springframeworkspring-aspects${spring.version}org.springframeworkspring-webmvc${spring.version}org.springframeworkspring-test${spring.version}testjunitjunit${junit.version}testorg.projectlomboklombok${lombok.version}providedcom.baomidoumybatis-plus${mybatis-plus.version}com.baomidoumybatis-plus-generator${mybatis-plus.version}testtrueorg.freemarkerfreemarker${freemarker.version}testtruecom.alibabadruid${druid.version}com.github.jsqlparserjsqlparser${jsqlparser.version}mysqlmysql-connector-java${mysql-connector.version}javax.servlet.jsp.jstljstl-api${jstl-api.version}javax.servletjavax.servlet-api${servlet-api.version}providedjavax.servlet.jspjavax.servlet.jsp-api${jsp-api.version}providedio.springfoxspringfox-swagger2${springfox-swagger.version}io.springfoxspringfox-swagger-ui${springfox-swagger.version}org.apache.commonscommons-lang3${commons-lang3.version}com.fasterxml.jackson.corejackson-databind${jackson.version}com.fasterxml.jackson.corejackson-annotations${jackson.version}compileorg.mapstructmapstruct${mapstruct.version}org.slf4jslf4j-api${slf4j.version}org.apache.logging.log4jlog4j-slf4j-impl${log4j.version}添加项目依赖org.springframeworkspring-context-supportorg.springframeworkspring-jdbcorg.springframeworkspring-aspectsorg.springframeworkspring-webmvcorg.springframeworkspring-testjunitjunitorg.projectlomboklombokcom.baomidoumybatis-pluscom.baomidoumybatis-plus-generatororg.freemarkerfreemarkercom.alibabadruidmysqlmysql-connector-javajavax.servlet.jsp.jstljstl-apijavax.servletjavax.servlet-apijavax.servlet.jspjavax.servlet.jsp-apiio.springfoxspringfox-swagger2io.springfoxspringfox-swagger-uiorg.apache.commonscommons-lang3com.fasterxml.jackson.corejackson-databindorg.mapstructmapstructorg.apache.logging.log4jlog4j-slf4j-impl管理ssmorg.apache.maven.pluginsmaven-clean-plugin${clean.plugin.version}org.apache.maven.pluginsmaven-resources-plugin${resources.plugin.version}${project.build.sourceEncoding}org.apache.maven.pluginsmaven-compiler-plugin${compiler.plugin.version}${maven.compiler.source}${maven.compiler.target}${project.build.sourceEncoding}org.projectlomboklombok${lombok.version}org.mapstructmapstruct-processor${mapstruct.version}-Amapstruct.defaultComponentModelspring-Amapstruct.unmappedTargetPolicyIGNOREorg.apache.maven.pluginsmaven-surefire-plugin${surefire.plugin.version}org.apache.maven.pluginsmaven-war-plugin${war.plugin.version}org.apache.maven.pluginsmaven-install-plugin${install.plugin.version}org.apache.maven.pluginsmaven-deploy-plugin${deploy.plugin.version}依赖配置好之后开始整合。先整合Log4j2日志在项目classpath目录(src/main/resources)下创建log4j2.xml文件添加Log4j2日志配置再整合 Spring 和 Mybatis本次还整合了 Mybatis Plus 开源框架新建 src/main/resources/mybatis/mybatis-config.xml 文件/pPUBLIC -//mybatis.org//DTD Config 3.0//ENhttp://mybatis.org/dtd/mybatis-3-config.dtd新建

MVC其中对日期类型返回json作了自定义格式化处理import com.fasterxml.jackson.core.JsonGenerator;import com.fasterxml.jackson.databind.JsonSerializer;import com.fasterxml.jackson.databind.ObjectMapper;import com.fasterxml.jackson.databind.SerializerProvider;import com.fasterxml.jackson.databind.module.SimpleModule;import java.io.IOException;import java.text.SimpleDateFormat;import

DateTimeFormatter.ofPattern(HH:mm:ss);/*** {inheritDoc}*/Overridepublic void serialize(LocalTime value, JsonGenerator jgen, SerializerProvider provider) throws IOException {jgen.writeString(TIME_FORMATTER.format(value));}}}还集成了 Swgger UI 方便接口调试import org.springframework.context.annotation.Bean;import springfox.documentation.builders.ApiInfoBuilder;import

http://www.springframework.org/schema/mvc/spring-mvc.xsdapplication/json;charsetUTF-8同时整合了MapStruct方便 Entity、DTO 和 VO 等之间的转换使用示例import com.example.ssm.entity.User;import com.example.ssm.vo.UserVo;import org.mapstruct.InheritInverseConfiguration;import org.mapstruct.Mapper;import org.mapstruct.Mapping;import org.mapstruct.Mappings;import java.util.List;Mapperpublic

java.time.LocalTime.now());map.put(java.time.LocalDateTime, java.time.LocalDateTime.now());return map;}}右上角“Add Configuration”添加 Tomcat 配置将项目部署信息配置好然后我们启动 Tomcat打开 http://localhost:8080/ssm如果正常应该显示如下界面点击界面上的超链接进入 Swagger UI 的界面。再测试一下 Spring 和 Mybatis 整合是否完成package com.example.ssm.controller;import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;import com.baomidou.mybatisplus.core.metadata.IPage;import com.baomidou.mybatisplus.core.metadata.OrderItem;import

userService.list(userLambdaQueryWrapper);}}在 Swagger UI 的界面里面测试接口返回正确另外Druid 的监控信息页面链接为http://localhost:8080/ssm/druid/index.html访问白名单、账号和密码在 web.xml 文件中配置。至此SSM 框架集成完毕测试通过因篇幅关系一些代码并没有在此文章中展现可到我的Gitee上看完整框架代码。
