maven工程搭建ssm框架詳細開發流程
阿新 • • 發佈：2018-12-17
一.開啟eclipse建立maven工程 這裡不多說了 二.在pom.xml里加入jar包 注意不同版本之間的jar包可能會有衝突,也不要全都加最新版本的jar包,到時解決起來很麻煩 直接點選官網搜尋jar包名下載相應jar包 基本所需的jar包給大家發出來 1.spring webmvc 4.3.7 2.spring jdbc 4.3.7 3.spring aspects 4.3.7 4.c3p0 0.9.5.2 5.mybatis 3.4.6 6.mysql 5.1.45 7.jstl 1.2 8.servlet-api 3.1.0 9.mybatis-spring 1.3.2 框架整合 10.junit 4.12 測試 11.mybatis-generator1.3.5 逆向工程 12.pagehelper 5.1.7 分頁外掛 13.jackson 2.9.6 返回json物件 14.hibernate-validator 5.4.1 後端驗證 14.fileupload 1.3.1 檔案上傳 這裡把我的pom.xml發出來
<!-- spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.7.RELEASE</version> </dependency> <!-- spring-jdbc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.7.RELEASE</version> </dependency> <!-- spring-aspects --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.3.7.RELEASE</version> </dependency> <!-- c3p0 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!-- mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.6</version> </dependency> <!-- mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.45</version> </dependency> <!-- jstl --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- javax.servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <!-- mybatis-spring --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.2</version> </dependency> <!-- junit --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- mybatis-generator-core --> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.5</version> </dependency> <!-- pagehelper --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>5.1.7</version> </dependency> <!-- jackson-databind --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.6</version> </dependency> <!-- hibernate-validator --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>5.4.1.Final</version> </dependency> <!-- commons-fileupload --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency>
三.配置檔案 springmvc的配置檔案 springMVC-servlet.xml 1.包掃描(只包含controller層) 2.靜態資源的處理方式 3.提供一些高階功能 4.檢視解析器
<!-- 包掃描（只包含controller） --> <context:component-scan base-package="com.zhiyou.bg.controller"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 靜態資源處理方式 --> <mvc:default-servlet-handler/> <!-- 高階功能 --> <mvc:annotation-driven></mvc:annotation-driven> <!-- 註冊攔截器 --> <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/**"/><!-- 過濾所有 --> <mvc:exclude-mapping path="/adminLogin"/><!-- 不過濾登入 --> <mvc:exclude-mapping path="/**/*.js"/><!-- 不過濾靜態資源 --> <mvc:exclude-mapping path="/**/*.css"/> <bean class="com.zhiyou.bg.interceptor.LoginInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> <!-- 檢視解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/"></property> <property name="suffix" value=".jsp"></property> </bean>
spring的配置檔案 application.xml 1引入屬性檔案 2.包掃描(排除controller層) 3.配置資料來源 4.配置SqlSessionFactory 5.配置mybatis介面的掃描 6.配置事物管理類 7.配置意見 8.配置切面 9.配置檔案上傳
<!-- 屬性檔案 -->
<context:property-placeholder location="classpath:db.properties" />
<!-- 包掃描 -->
<context:component-scan base-package="com.zhiyou.bg">
<!-- 排除controller層 -->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 資料來源 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="driverClass" value="${jdbc.driver}"></property>
</bean>
<!-- 配置sqlSessionFectoryBean -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<!-- <property name="configLocation" value="classpath:mybatis.xml"></property> -->
<property name="mapperLocations" value="classpath:com/zhiyou/bg/mapper/*.xml"></property>
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties">
<!--使用下面的方式配置引數，一行配置一個 -->
<value>reasonable=true</value>
</property>
</bean>
</array>
</property>
</bean>
<!-- mybatis介面的掃描 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.zhiyou.bg.dao"></property>
</bean>
<!-- 配置事務管理類 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 配置意見 -->
<tx:advice id="advice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="query*" read-only="true"/>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
<!-- 切面 -->
<aop:config>
<aop:pointcut expression="execution(* com.zhiyou.bg.*.*(..))" id="pointcut"/>
<aop:advisor advice-ref="advice" pointcut-ref="pointcut"/>
</aop:config>
該配置檔案裡的<property name="configLocation" value="classpath:mybatis.xml"></property>是引用mybatis的配置檔案,mybatis的配置基本上都能在該配置檔案裡寫全,所以不需要再寫mybatis的配置檔案.
該配置檔案裡的
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties">
<!--使用下面的方式配置引數，一行配置一個 -->
<value>reasonable=true</value>
</property>
</bean>
</array>
</property>
是設定pagehelper分頁外掛的
屬性檔案 db.properties
jdbc.user=root
jdbc.password=root
jdbc.url=jdbc:mysql://localhost:3306/crowdfunding?characterEncoding=utf-8
jdbc.driver=com.mysql.jdbc.Driver
以上三個檔案全部放在src/main/resources目錄下 三.web.xml 1.配置編碼的過濾器 2.DispatcherServlet配置springMvc 3. 配置spring啟動的listener
<!-- 配置編碼的過濾器 -->
<filter>
<filter-name>encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置springMVC -->
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springMvc-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 配置spring啟動的listener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
四.逆向工程 1.配置檔案 mybatisGenerator.xml 2.測試驅動 該配置檔案直接建在工程下,與pom.xml同級
<generatorConfiguration>
<classPathEntry location="D:\ziliao\mysql-connector-java-5.1.45.jar" />
<context id="DB2Tables" targetRuntime="MyBatis3">
<!-- 去掉註釋 -->
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!-- 資料庫資訊源 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/ssm"
userId="root"
password="root">
</jdbcConnection>
<javaTypeResolver >
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<javaModelGenerator targetPackage="com.zhiyou.lsh.bean" targetProject=".\src\main\java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<sqlMapGenerator targetPackage="com.zhiyou.lsh.mapper" targetProject=".\src\main\java">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<javaClientGenerator type="XMLMAPPER" targetPackage="com.zhiyou.lsh.dao" targetProject=".\src\main\java">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<table tableName="emp" domainObjectName="Emp" >
<property name="useActualColumnNames" value="true"/>
<generatedKey column="ID" sqlStatement="DB2" identity="true" />
<columnOverride column="DATE_FIELD" property="startDate" />
<ignoreColumn column="FRED" />
<columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />
</table>
<table tableName="dept" domainObjectName="Dept" >
<property name="useActualColumnNames" value="true"/>
<generatedKey column="ID" sqlStatement="DB2" identity="true" />
<columnOverride column="DATE_FIELD" property="startDate" />
<ignoreColumn column="FRED" />
<columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />
</table>
</context>
</generatorConfiguration>
寫我們的測試類來驅動生成
public class Test1 {
public static void main(String[] args) throws Exception{
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
File configFile = new File("mybatisGenerator.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
myBatisGenerator.generate(null);
}
}
五. 在dao層和mapper對映中,增加自己想要的方法 mybatis是沒有連結串列查詢的,我們可以自己增加自己想要的連結串列查詢sql語句或者其他 六. service層編寫介面和介面實現類,編寫自己的方法來呼叫dao層的方法 然後可以先寫測試類來測試我們service層的方法是否可行 七. 再通過controller層編寫自己的方法來呼叫service層的方法並連線到jsp頁面 八. 最後編寫我們的jsp頁面
