收集整理的這篇文章主要介紹了
大数据WEB阶段 Maven与SSM框架整合
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
Maven整合SSM框架
零、 目錄
- Maven整合SSM
- 常見的問題
- 以及一些優化
一、 Maven整合SSM
配置pom.xml文件 并在pom.xml文件中添加tomcat插件
pom.xml文件中一般需要使用的依賴
<!-- 集中定義依賴版本號 --> <properties><junit.version>4.12</junit.version><spring.version>4.2.3.RELEASE</spring.version><mybatis.version>3.2.8</mybatis.version><mybatis.spring.version>1.2.2</mybatis.spring.version><mybatis.paginator.version>1.2.15</mybatis.paginator.version><mysql.version>5.1.32</mysql.version><bonecp-spring.version>0.8.0.RELEASE</bonecp-spring.version><druid.version>1.0.9</druid.version><mapper.version>2.3.2</mapper.version><pagehelper.version>3.4.2</pagehelper.version><jsqlparser.version>0.9.1</jsqlparser.version><slf4j.version>1.6.4</slf4j.version><jstl.version>1.2</jstl.version><servlet-api.version>2.5</servlet-api.version><jsp-api.version>2.0</jsp-api.version> </properties><dependencies><!-- Spring --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency> <dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${spring.version}</version></dependency><!-- Mybatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>${mybatis.spring.version}</version></dependency><dependency><groupId>com.github.miemiedev</groupId><artifactId>mybatis-paginator</artifactId><version>${mybatis.paginator.version}</version></dependency> <!-- 通用Mapper，所有的單表的代碼都不用編寫 --><dependency><groupId>com.github.abel533</groupId><artifactId>mapper</artifactId><version>${mapper.version}</version></dependency><!-- Oracle版權問題，maven目錄必須自己手動建立 --><dependency> <groupId>com.oracle</groupId><artifactId>ojdbc6</artifactId><version>11.1.0.7.0</version></dependency><!-- MySql --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency><!-- 超高性能連接池 --><dependency><groupId>com.zaxxer</groupId><artifactId>HikariCP-java6</artifactId><version>2.3.9</version><scope>compile</scope></dependency> <!-- Apache Shiro 權限架構 --><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-all</artifactId><version>1.2.3</version></dependency> <!-- 分頁插件 --><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId><version>${pagehelper.version}</version></dependency><dependency><groupId>com.github.jsqlparser</groupId><artifactId>jsqlparser</artifactId><version>${jsqlparser.version}</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency><!-- JSP相關 --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>${jstl.version}</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>${servlet-api.version}</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jsp-api</artifactId><version>${jsp-api.version}</version><scope>provided</scope></dependency><!-- 字符加密、解密 --><dependency><groupId>commons-codec</groupId><artifactId>commons-codec</artifactId><version>1.9</version></dependency><!-- 數據校驗 --><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-validator</artifactId><version>5.1.3.Final</version></dependency> <!-- 數據庫連接池 --><dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.2.1</version></dependency><!-- 文件上傳 --><!-- https://mvnrepository.com/artifact/commons-fileupload/commons-fileupload --><dependency><groupId>commons-fileupload</groupId><artifactId>commons-fileupload</artifactId><version>1.3.1</version></dependency> </dependencies>在pom.xml文件中添加tomcat插件

web.xml文件中添加 servlet分發器 、 亂碼過濾器 、 引入spring配置文件

如果maven項目中的jsp頁面中el表達式不生效則需要在page標簽中添加屬性
isELIgnored=“false”三、優化
但是這樣會出現頁面訪問css等靜態資源時被攔截導致不能加載的問題 ， 需要在springmvc-config.xml配置文件中添加
<mvc:default-servlet-handler/>在spring與mybatis整合配置文件中可以直接為包起一個別名 ， 簡化了為類起別名的操作 。
<!-- 配置mybatis --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><!-- 配置數據源 --><property name="dataSource" ref = "datassource"></property><!-- 注入mybatis核心配置文件 --><property name="configLocation" value="classpath:/mybatis/sqlMapConfig.xml"></property><!-- 注入映射文件 --> <!-- 如果該目錄為空 ， 則會報錯 --><!-- <property name="mapperLocations" value="classpath:/mybatis/mappers/*.xml"></property> --><!-- 配置包別名 --><property name="typeAliasesPackage" value="com.tj.ht.pojo" /></bean>mybatis中開啟駝峰自動映射 如： 數據庫中標字段aaa_bbb 會自動映射為實體類中的屬性aaaBbb
<settings><!-- 配置緩存 --><setting name="cacheEnabled" value="true"/><!-- 配置自動駝峰映射 --><setting name="mapUnderscoreToCamelCase" value="true"/></settings>總結
