篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了idea搭建ssm框架相关的知识，希望对你有一定的参考价值。
1、基本概念
1.1、Spring
Spring是一个开源框架，Spring是于2003 年兴起的一个轻量级的Java 开发框架，由Rod Johnson 在其著作Expert One-On-One J2EE Development and Design中阐述的部分理念和原型衍生而来。它是为了解决企业应用开发的复杂性而创建的。Spring使用基本的JavaBean来完成以前只可能由EJB完成的事情。然而，Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。 简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。
1.2、SpringMVC
Spring MVC属于SpringFrameWork的后续产品，已经融合在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。
1.3、MyBatis
MyBatis 本是apache的一个开源项目iBatis, 2010年这个项目由apache software foundation 迁移到了google code，并且改名为MyBatis 。MyBatis是一个基于Java的持久层框架。iBATIS提供的持久层框架包括SQL Maps和Data Access Objects（DAO）MyBatis 消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射，将接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java对象）映射成数据库中的记录。
2、开发环境搭建以及创建Maven Web项目
1.jdk1.8
2.idea
3.maven tomcat
settings.xml

It can be specified at two levels: 24 | 25 | 1. User Level. This settings.xml file provides configuration for a single user, 26 | and is normally provided in ${user.home}/.m2/settings.xml. 27 | 28 | NOTE: This location can be overridden with the CLI option: 29 | 30 | -s /path/to/user/settings.xml 31 | 32 | 2. Global Level. This settings.xml file provides configuration for all Maven 33 | users on a machine (assuming they‘re all using the same Maven 34 | installation). It‘s normally provided in 35 | ${maven.conf}/settings.xml. 36 | 37 | NOTE: This location can be overridden with the CLI option: 38 | 39 | -gs /path/to/global/settings.xml 40 | 41 | The sections in this sample file are intended to give you a running start at 42 | getting the most out of your Maven installation. Where appropriate, the default 43 | values (values used when the setting is not specified) are provided. 44 | 45 |--> 46 <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 47 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 48 xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> 49 <!-- localRepository 50 | The path to the local repository maven will use to store artifacts. 51 | 52 | Default: ${user.home}/.m2/repository 53 <localRepository>/path/to/local/repo</localRepository> 54 --> 55 <localRepository>D:DevelopMvnRepo</localRepository> 56 57 <!-- interactiveMode 58 | This will determine whether maven prompts you when it needs input. If set to false, 59 | maven will use a sensible default value, perhaps based on some other setting, for 60 | the parameter in question. 61 | 62 | Default: true 63 <interactiveMode>true</interactiveMode> 64 --> 65 66 <!-- offline 67 | Determines whether maven should attempt to connect to the network when executing a build. 68 | This will have an effect on artifact downloads, artifact deployment, and others. 69 | 70 | Default: false 71 <offline>false</offline> 72 --> 73 74 <!-- pluginGroups 75 | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e. 76 | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers 77 | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list. 78 |--> 79 <pluginGroups> 80 <!-- pluginGroup 81 | Specifies a further group identifier to use for plugin lookup. 82 <pluginGroup>com.your.plugins</pluginGroup> 83 --> 84 </pluginGroups> 85 86 <!-- proxies 87 | This is a list of proxies which can be used on this machine to connect to the network. 88 | Unless otherwise specified (by system property or command-line switch), the first proxy 89 | specification in this list marked as active will be used. 90 |--> 91 <proxies> 92 <!-- proxy 93 | Specification for one proxy, to be used in connecting to the network. 94 | 95 <proxy> 96 <id>optional</id> 97 <active>true</active> 98 <protocol>http</protocol> 99 <username>proxyuser</username> 100 <password>proxypass</password> 101 <host>proxy.host.net</host> 102 <port>80</port> 103 <nonProxyHosts>local.net|some.host.com</nonProxyHosts> 104 </proxy> 105 --> 106 </proxies> 107 108 <!-- servers 109 | This is a list of authentication profiles, keyed by the server-id used within the system. 110 | Authentication profiles can be used whenever maven must make a connection to a remote server. 111 |--> 112 <servers> 113 <!-- server 114 | Specifies the authentication information to use when connecting to a particular server, identified by 115 | a unique name within the system (referred to by the ‘id‘ attribute below). 116 | 117 | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are 118 | used together. 119 | 120 <server> 121 <id>deploymentRepo</id> 122 <username>repouser</username> 123 <password>repopwd</password> 124 </server> 125 --> 126 127 <!-- Another sample, using keys to authenticate. 128 <server> 129 <id>siteServer</id> 130 <privateKey>/path/to/private/key</privateKey> 131 <passphrase>optional; leave empty if not used.</passphrase> 132 </server> 133 --> 134 </servers> 135 136 <!-- mirrors 137 | This is a list of mirrors to be used in downloading artifacts from remote repositories. 138 | 139 | It works like this: a POM may declare a repository to use in resolving certain artifacts. 140 | However, this repository may have problems with heavy traffic at times, so people have mirrored 141 | it to several places. 142 | 143 | That repository definition will have a unique id, so we can create a mirror reference for that 144 | repository, to be used as an alternate download site. The mirror site will be the preferred 145 | server for that repository. 146 |--> 147 <mirrors> 148 <mirror> 149 <id>nexus-aliyun</id> 150 <mirrorOf>central</mirrorOf> 151 <name>Nexus aliyun</name> 152 <url>http://maven.aliyun.com/nexus/content/repositories/central</url> 153 </mirror> 154 <!-- mirror 155 | Specifies a repository mirror site to use instead of a given repository. The repository that 156 | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used 157 | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. 158 | 159 <mirror> 160 <id>mirrorId</id> 161 <mirrorOf>repositoryId</mirrorOf> 162 <name>Human Readable Name for this Mirror.</name> 163 <url>http://my.repository.com/repo/path</url> 164 </mirror> 165 --> 166 </mirrors> 167 168 <!-- profiles 169 | This is a list of profiles which can be activated in a variety of ways, and which can modify 170 | the build process. Profiles provided in the settings.xml are intended to provide local machine- 171 | specific paths and repository locations which allow the build to work in the local environment. 172 | 173 | For example, if you have an integration testing plugin - like cactus - that needs to know where 174 | your Tomcat instance is installed, you can provide a variable here such that the variable is 175 | dereferenced during the build process to configure the cactus plugin. 176 | 177 | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles 178 | section of this document (settings.xml) - will be discussed later. Another way essentially 179 | relies on the detection of a system property, either matching a particular value for the property, 180 | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a 181 | value of ‘1.4‘ might activate a profile when the build is executed on a JDK version of ‘1.4.2_07‘. 182 | Finally, the list of active profiles can be specified directly from the command line. 183 | 184 | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact 185 | repositories, plugin repositories, and free-form properties to be used as configuration 186 | variables for plugins in the POM. 187 | 188 |--> 189 <profiles> 190 <!-- profile 191 | Specifies a set of introductions to the build process, to be activated using one or more of the 192 | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/> 193 | or the command line, profiles have to have an ID that is unique. 194 | 195 | An encouraged best practice for profile identification is to use a consistent naming convention 196 | for profiles, such as ‘env-dev‘, ‘env-test‘, ‘env-production‘, ‘user-jdcasey‘, ‘user-brett‘, etc. 197 | This will make it more intuitive to understand what the set of introduced profiles is attempting 198 | to accomplish, particularly when you only have a list of profile id‘s for debug. 199 | 200 | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo. 201 <profile> 202 <id>jdk-1.4</id> 203 204 <activation> 205 <jdk>1.4</jdk> 206 </activation> 207 208 <repositories> 209 <repository> 210 <id>jdk14</id> 211 <name>Repository for JDK 1.4 builds</name> 212 <url>http://www.myhost.com/maven/jdk14</url> 213 <layout>default</layout> 214 <snapshotPolicy>always</snapshotPolicy> 215 </repository> 216 </repositories> 217 </profile> 218 --> 219 220 <!-- 221 | Here is another profile, activated by the system property ‘target-env‘ with a value of ‘dev‘, 222 | which provides a specific path to the Tomcat instance. To use this, your plugin configuration 223 | might hypothetically look like: 224 | 225 | ... 226 | <plugin> 227 | <groupId>org.myco.myplugins</groupId> 228 | <artifactId>myplugin</artifactId> 229 | 230 | <configuration> 231 | <tomcatLocation>${tomcatPath}</tomcatLocation> 232 | </configuration> 233 | </plugin> 234 | ... 235 | 236 | NOTE: If you just wanted to inject this configuration whenever someone set ‘target-env‘ to 237 | anything, you could just leave off the <value/> inside the activation-property. 238 | 239 <profile> 240 <id>env-dev</id> 241 242 <activation> 243 <property> 244 <name>target-env</name> 245 <value>dev</value> 246 </property> 247 </activation> 248 249 <properties> 250 <tomcatPath>/path/to/tomcat/instance</tomcatPath> 251 </properties> 252 </profile> 253 --> 254 </profiles> 255 256 <!-- activeProfiles 257 | List of profiles that are active for all builds. 258 | 259 <activeProfiles> 260 <activeProfile>alwaysActiveProfile</activeProfile> 261 <activeProfile>anotherAlwaysActiveProfile</activeProfile> 262 </activeProfiles> 263 --> 264 </settings>
3.开始建立maven工程
配置正确的话就会出现 刚开始配maven工程可能会久一点
3.1 在pom.xml中引入jar包
之后的内容修改一下就好了，我把pom.xml文件放上

成功导入jar就是这样，如果没有就点击idea右下角右边的按钮Enable import
3.2 目录结构配置
在src-main目录创建一个java和resource
并且在左上角File-Project Structure-Modules-Source
之后apply-ok一下就好了
以上是关于idea搭建ssm框架的主要内容，如果未能解决你的问题，请参考以下文章
