前言

根据自己的环境参考狂神的视频进行了SSM框架整合,用于备忘

SSM框架整合步骤

1. 创建数据库

2. IDEA创建maven项目.在pom.xml中设设置java conpiler版本(jdk13)

3. 导入依赖 jnuit 数据库驱动 数据库连接 Severlet JSp

4. maven 资源过滤

<? xml version = "1.0" encoding = "UTF-8" ?> <project xmlns = "http://maven.apache.org/POM/4.0.0" xmlns:xsi = "http://HdhCmsTestw3.org/2001/XMLSchema-instance" xsi:schemaLocation = "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" > <modelVersion> 4.0.0 </modelVersion> <build> <resources> <resource> <directory> src/main/java </directory> <includes> <include> **/*.properties </include> <include> **/*.xml </include> </includes> <filtering> false </filtering> </resource> <resource> <directory> src/main/resources </directory> <includes> <include> **/*.properties </include> <include> **/*.xml </include> </includes> <filtering> false </filtering> </resource> </resources> </build>   <groupId> org.example </groupId> <artifactId> ssm </artifactId> <version> 1.0-SNAPSHOT </version> <properties> <maven测试数据piler.source> 13 </maven测试数据piler.source> <maven测试数据piler.target> 13 </maven测试数据piler.target> </properties> <dependencies> <!--Junit--> <dependency> <groupId> junit </groupId> <artifactId> junit </artifactId> <version> 4.12 </version> </dependency> <!--数据库驱动--> <dependency> <groupId> mysql </groupId> <artifactId> mysql-connector-java </artifactId> <version> 5.1.47 </version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId> com.mchange </groupId> <artifactId> c3p0 </artifactId> <version> 0.9.5.2 </version> </dependency>   <!--Servlet - JSP --> <dependency> <groupId> javax.servlet </groupId> <artifactId> servlet-api </artifactId> <version> 2.5 </version> </dependency> <dependency> <groupId> javax.servlet.jsp </groupId> <artifactId> jsp-api </artifactId> <version> 2.2 </version> </dependency> <dependency> <groupId> javax.servlet </groupId> <artifactId> jstl </artifactId> <version> 1.2 </version> </dependency>   <!--Mybatis--> <dependency> <groupId> org.mybatis </groupId> <artifactId> mybatis </artifactId> <version> 3.5.2 </version> </dependency> <dependency> <groupId> org.mybatis </groupId> <artifactId> mybatis-spring </artifactId> <version> 2.0.6 </version> </dependency>   <!--Spring--> <dependency> <groupId> org.springframework </groupId> <artifactId> spring-webmvc </artifactId> <version> 5.3.4 </version> </dependency> <dependency> <groupId> org.springframework </groupId> <artifactId> spring-jdbc </artifactId> <version> 5.3.4 </version> </dependency> </dependencies>   </project>

5. 创建两个项目的目录结构以及Spring 和 Mybatis的配置文件

<? xml version = "1.0" encoding = "UTF-8" ?> <beans xmlns = "http://HdhCmsTestspringframework.org/schema/beans" xmlns:xsi = "http://HdhCmsTestw3.org/2001/XMLSchema-instance" xsi:schemaLocation = "http://HdhCmsTestspringframework.org/schema/beans http://HdhCmsTestspringframework.org/schema/beans/spring-beans.xsd" >   </beans> <? xml version = "1.0" encoding = "UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration>   </configuration>

Mybatis

6. 配置数据库属性

jdbc . driver = com . mysql . jdbc . Driver jdbc . url = jdbc : mysql : //localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC jdbc . username = root jdbc . password = root

7. 创建Book实体类(使用lombok插件),编写Dao层mapper接口,在mybatis配置中注册mapper

package com . projectname . pojo ;   import lombok . AllArgsConstructor ; import lombok . Data ; import lombok . NoArgsConstructor ;   @Data @AllArgsConstructor @NoArgsConstructor public class Book { private int bookID ; private String bookName ; private int bookCounts ; private String detail ;   } package com . projectname . dao ;   import com . projectname . pojo . Book ;   import java . util . List ;   public interface DaoBook { //增加一个Book int addBook ( Book book );   //根据id删除一个Book int deleteBookById ( int id );   //更新Book int updateBook ( Book books );   //根据id查询,返回一个Book Book queryBookById ( int id );   //查询全部Book,返回list集合 List < Book > queryAllBook (); } <? xml version = "1.0" encoding = "UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">   <mapper namespace = "com.kuang.dao.BookMapper" >   <!--增加一个Book--> <insert id = "addBook" parameterType = "Books" > insert into ssmbuild.books(bookName,bookCounts,detail) values (#{bookName}, #{bookCounts}, #{detail}) </insert>   <!--根据id删除一个Book--> <delete id = "deleteBookById" parameterType = "int" > delete from ssmbuild.books where bookID=#{bookID} </delete>   <!--更新Book--> <update id = "updateBook" parameterType = "Books" > update ssmbuild.books set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail} where bookID = #{bookID} </update>   <!--根据id查询,返回一个Book--> <select id = "queryBookById" resultType = "Books" > select * from ssmbuild.books where bookID = #{bookID} </select>   <!--查询全部Book--> <select id = "queryAllBook" resultType = "Books" > SELECT * from ssmbuild.books </select>   </mapper> <? xml version = "1.0" encoding = "UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <mappers> <mapper resource = "com/projectname/dao/BookMapper.xml" /> </mappers> </configuration>

8. 编写service层的接口和实现类代码

package com . projectname . service ;   import com . projectname . pojo . Book ;   import java . util . List ;   public interface BookService { //增加一个Book int addBook ( Book book ); //根据id删除一个Book int deleteBookById ( int id ); //更新Book int updateBook ( Book books ); //根据id查询,返回一个Book Book queryBookById ( int id ); //查询全部Book,返回list集合 List < Book > queryAllBook (); } package com . projectname . service ;   import com . projectname . dao . BookMapper ; import com . projectname . pojo . Book ;   import java . util . List ;   public class BookServiceImpl implements BookService {   //调用dao层的操作，设置一个set接口，方便Spring管理 private BookMapper bookMapper ;   public void setBookMapper ( BookMapper bookMapper ) { this . bookMapper = bookMapper ; }   public int addBook ( Book book ) { return bookMapper . addBook ( book ); }   public int deleteBookById ( int id ) { return bookMapper . deleteBookById ( id ); }   public int updateBook ( Book books ) { return bookMapper . updateBook ( books ); }   public Book queryBookById ( int id ) { return bookMapper . queryBookById ( id ); }   public List < Book > queryAllBook () { return bookMapper . queryAllBook (); } }

Spring

9. 使用Spring编写Mybatis配置文件:spring-dao.xml

<? xml version = "1.0" encoding = "UTF-8" ?> <beans xmlns = "http://HdhCmsTestspringframework.org/schema/beans" xmlns:xsi = "http://HdhCmsTestw3.org/2001/XMLSchema-instance" xmlns:context = "http://HdhCmsTestspringframework.org/schema/context" xsi:schemaLocation = "http://HdhCmsTestspringframework.org/schema/beans http://HdhCmsTestspringframework.org/schema/beans/spring-beans.xsd http://HdhCmsTestspringframework.org/schema/context https://HdhCmsTestspringframework.org/schema/context/spring-context.xsd" > <context:property-placeholder location = "classpath:database.properties" /> <!-- 2.数据库连接池 --> <!--数据库连接池 dbcp 半自动化操作 不能自动连接 c3p0 自动化操作（自动的加载配置文件 并且设置到对象里面） --> <bean id = "dataSource" class = "com.mchange.v2.c3p0.ComboPooledDataSource" > <!-- 配置连接池属性 --> <property name = "driverClass" value = "${jdbc.driver}" /> <property name = "jdbcUrl" value = "${jdbc.url}" /> <property name = "user" value = "${jdbc.username}" /> <property name = "password" value = "${jdbc.password}" /> <!-- c3p0连接池的私有属性 --> <property name = "maxPoolSize" value = "30" /> <property name = "minPoolSize" value = "10" /> <!-- 关闭连接后不自动commit --> <property name = "autoCommitOnClose" value = "false" /> <!-- 获取连接超时时间 --> <property name = "checkoutTimeout" value = "10000" /> <!-- 当获取连接失败重试次数 --> <property name = "acquireRetryAttempts" value = "2" /> </bean> <!-- 3.配置SqlSessionFactory对象 --> <bean id = "sqlSessionFactory" class = "org.mybatis.spring.SqlSessionFactoryBean" > <!-- 注入数据库连接池 --> <property name = "dataSource" ref = "dataSource" /> <!-- 配置MyBaties全局配置文件:mybatis-config.xml --> <property name = "configLocation" value = "classpath:mybatis-configuration.xml" /> </bean> <!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 --> <!--解释 ：https://HdhCmsTestcnblogs测试数据/jpfss/p/7799806.html--> <bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer" > <!-- 注入sqlSessionFactory --> <property name = "sqlSessionFactoryBeanName" value = "sqlSessionFactory" /> <!-- 给出需要扫描Dao接口包 --> <property name = "basePackage" value = "com.projectname.dao" /> </bean> </beans>

10. Spring 整合service层

spring-service

<? xml version = "1.0" encoding = "UTF-8" ?> <beans xmlns = "http://HdhCmsTestspringframework.org/schema/beans" xmlns:xsi = "http://HdhCmsTestw3.org/2001/XMLSchema-instance" xmlns:context = "http://HdhCmsTestspringframework.org/schema/context" xsi:schemaLocation = "http://HdhCmsTestspringframework.org/schema/beans http://HdhCmsTestspringframework.org/schema/beans/spring-beans.xsd http://HdhCmsTestspringframework.org/schema/context https://HdhCmsTestspringframework.org/schema/context/spring-context.xsd" >   <!-- 扫描service相关的bean --> <context:component-scan base-package = "com.projectname.service" />   <!--BookServiceImpl注入到IOC容器中--> <bean id = "BookServiceImpl" class = "com.projectname.service.BookServiceImpl" > <property name = "bookMapper" ref = "bookMapper" /> </bean>   <!-- 配置事务管理器 --> <bean id = "transactionManager" class = "org.springframework.jdbc.datasource.DataSourceTransactionManager" > <!-- 注入数据库连接池 --> <property name = "dataSource" ref = "dataSource" /> </bean>   </beans>

Spring MVC层

11. configuate the web.xml

<? xml version = "1.0" encoding = "UTF-8" ?> <web-app xmlns = "http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi = "http://HdhCmsTestw3.org/2001/XMLSchema-instance" xsi:schemaLocation = "http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version = "4.0" > <!-- 配置SpringMVC --> <!-- 1.开启SpringMVC注解驱动 --> <servlet> <servlet-name> DispatcherServlet </servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name> contextConfigLocation </param-name> <!--一定要注意:我们这里加载的是总的配置文件，之前被这里坑了！--> <param-value> classpath:applicationContext.xml </param-value> </init-param> <load-on-startup> 1 </load-on-startup> </servlet> <servlet-mapping> <servlet-name> DispatcherServlet </servlet-name> <url-pattern> / </url-pattern> </servlet-mapping>   <!--encodingFilter--> <filter> <filter-name> encodingFilter </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> encodingFilter </filter-name> <url-pattern> /* </url-pattern> </filter-mapping>   <!--Session过期时间--> <session-config> <session-timeout> 15 </session-timeout> </session-config> </web-app>

12. spring-mvc.xml

<? xml version = "1.0" encoding = "UTF-8" ?> <beans xmlns = "http://HdhCmsTestspringframework.org/schema/beans" xmlns:xsi = "http://HdhCmsTestw3.org/2001/XMLSchema-instance" xmlns:mvc = "http://HdhCmsTestspringframework.org/schema/mvc" xmlns:context = "http://HdhCmsTestspringframework.org/schema/context" xsi:schemaLocation = "http://HdhCmsTestspringframework.org/schema/beans http://HdhCmsTestspringframework.org/schema/beans/spring-beans.xsd http://HdhCmsTestspringframework.org/schema/mvc https://HdhCmsTestspringframework.org/schema/mvc/spring-mvc.xsd http://HdhCmsTestspringframework.org/schema/context https://HdhCmsTestspringframework.org/schema/context/spring-context.xsd" > <!-- 配置SpringMVC --> <!-- 1.开启SpringMVC注解驱动 --> <mvc:annotation-driven /> <!-- 2.静态资源默认servlet配置--> <mvc:default-servlet-handler/>   <!-- 3.配置jsp 显示ViewResolver视图解析器 --> <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver" > <property name = "viewClass" value = "org.springframework.web.servlet.view.JstlView" /> <property name = "prefix" value = "/WEB-INF/jsp/" /> <property name = "suffix" value = ".jsp" /> </bean> <!-- 4.扫描web相关的bean --> <context:component-scan base-package = "com.projectname.controller" /> </beans>

13. configuate applicationContext.xml

<? xml version = "1.0" encoding = "UTF-8" ?> <beans xmlns = "http://HdhCmsTestspringframework.org/schema/beans" xmlns:xsi = "http://HdhCmsTestw3.org/2001/XMLSchema-instance" xmlns:mvc = "http://HdhCmsTestspringframework.org/schema/mvc" xmlns:context = "http://HdhCmsTestspringframework.org/schema/context" xsi:schemaLocation = "http://HdhCmsTestspringframework.org/schema/beans http://HdhCmsTestspringframework.org/schema/beans/spring-beans.xsd http://HdhCmsTestspringframework.org/schema/mvc https://HdhCmsTestspringframework.org/schema/mvc/spring-mvc.xsd http://HdhCmsTestspringframework.org/schema/context https://HdhCmsTestspringframework.org/schema/context/spring-context.xsd" >   <import resource = "spring-dao.xml" /> <import resource = "spring-service.xml" /> <import resource = "spring-mvc.xml" />   </beans>

一些杂七杂八的配置

14. 添加日志功能

<settings> <setting name = "logImpl" value = "STDOUT_LOGGING" /> </settings>

15. add lib

File -> Project Structure->Artifacts
Type -> Bundle

new directory lib
