记录搭建ssm项目
搞java也快3年了，搭建一个ssm居然有点吃力。
参考链接：https://blog.csdn.net/gebitan505/article/details/44455235/
环境准备：jdk8、maven、idea
1、新建maven项目，增加web模块
2、集成spring
导入基本jar包：
<properties>
<java-version>1.8</java-version>
<spring-verion>4.3..RELEASE</spring-verion>
<mybatis-version>3.4.</mybatis-version>
</properties> <dependencies> <!-- spring -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring-verion}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring-verion}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>${spring-verion}</version>
</dependency>
<dependency>
<groupId>org.springframework.batch</groupId>
<artifactId>spring-batch-infrastructure</artifactId>
<version>3.0..RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring-verion}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>${spring-verion}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring-verion}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring-verion}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring-verion}</version>
</dependency> <!-- aop dependencies-->
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.</version>
</dependency>
<!-- bean validate -->
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1..Final</version>
</dependency>
2、集成mybatis
spring的话什么也不写的话就只需要书写一下ApplicationContext.xml即可。所以直接准备与mybatis集成
导入jar：
<!-- mybatis -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>${mybatis-version}</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.3.</version>
</dependency>
<!-- mysql -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.</version>
</dependency>
然后写好简单的目录结构：
书写spring-mybatis的配置文件：
包含功能：spring的基本扫描，datascource的管理，sessionFactory的配置，transManage的配置，mybatis-mapper的扫描
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- spring和mybatis进行整合。主要进行扫描、注入、配置数据库 --> <context:property-placeholder location="classpath:config/props/jdbc.properties" ignore-unresolvable="true"/> <!-- 扫描 -->
<context:component-scan base-package="com.testweb">
<!-- 避免重复扫描controller -->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan> <!-- 配置数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName"><value>${jdbc.driverClassName}</value></property>
<property name="url"><value>${jdbc.url}</value></property>
<property name="username"><value>${jdbc.username}</value></property>
<property name="password"><value>${jdbc.password}</value></property>
</bean> <!-- session工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/testweb/dal/mapper/UserDOMapper.xml"></property>
</bean> <!-- 扫描mapper接口 -->
<!-- 使用tk.mybatis所以注释掉mybatis的
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.testweb.dal.mapper"/>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
</bean>
-->
<bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.testweb.dal.mapper"/>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
</bean> <!-- 事务管理 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean> </beans>
tk.mybatis是通用mapper，为了简化xml编写的一个第三方插件
<!-- tk.mybatis -->
<dependency>
<groupId>tk.mybatis</groupId>
<artifactId>mapper</artifactId>
<version>4.0.</version>
</dependency>
然后准备测试一下与spring与mybatis的整合是否成功
使用mybatis-generator进行实体的生成等。
依赖：
<!-- mybatis-generator -->
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.</version>
</dependency>
<!-- junit -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
测试用到junit所以干脆把junit也带过来。
测试使用junit与spring集成，需要spring-test包：
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring-verion}</version>
</dependency>
mybatis-generator.xml：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<!--数据库驱动-->
<classPathEntry location="D:\idea\repository\mysql\mysql-connector-java\8.0.11\mysql-connector-java-8.0.11.jar"/>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--数据库链接地址账号密码-->
<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/testweb?useSSL=false" userId="root" password="961012gz">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!--生成Model类存放位置-->
<javaModelGenerator targetPackage="com.testweb.dal.model" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!--生成映射文件存放位置-->
<sqlMapGenerator targetPackage="com.testweb.dal.mapper" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!--生成Dao类存放位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.testweb.dal.mapper" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!--生成对应表及类名-->
<table tableName="t_user" domainObjectName="UserDO" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>
mybatis-generator为了idea运行配置插件：
<!-- mybatis逆向工程 -->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.</version>
<configuration>
<!--配置文件的位置-->
<configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
</plugin>
测试类：
package build; import com.testweb.common.enums.UserLockStatusEnum;
import com.testweb.dal.mapper.UserDOMapper;
import com.testweb.dal.model.UserDO;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; /**
* @author zhen
* @Date 2018/5/23 13:36
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:config/spring/spring-mybatis.xml"})
public class TestMyBatis { @Autowired
private UserDOMapper userDOMapper; @Test
public void testAddUser(){
UserDO userDO = new UserDO();
userDO.setName("admin");
userDO.setPassword("");
userDO.setPhone("");
userDO.setStatus(UserLockStatusEnum.NORMAL.getCode());
int i = userDOMapper.insert(userDO);
System.out.println(i);
}
}
然后进行spring与mvc的耦合：
写spring-mvc的配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tool http://www.springframework.org/schema/tool/spring-tool.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <mvc:annotation-driven></mvc:annotation-driven>
<!-- 扫描Controller -->
<context:component-scan base-package="com.testweb.controller"></context:component-scan> <!-- 使用mvc:annotation-driven替代，它有默认配置
注解处理器适配器
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"></bean>
注解处理器映射器
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>
JSON转换器，支持@RequestBody与@ResponseBody
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-</value>
</list>
</property>
</bean>
--> <!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!-- 后缀 -->
<property name="suffix" value=".jsp"/>
</bean> <!-- 文件上传 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 上传文件大小上限，单位为字节（10MB） -->
<property name="maxUploadSize">
<value></value>
</property>
<!-- 请求的编码格式，必须和jSP的pageEncoding属性一致，以便正确读取表单的内容，默认为ISO-- -->
<property name="defaultEncoding">
<value>UTF-</value>
</property>
</bean> </beans>
对了，配置log4j
配置文件：
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n #文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = E:/logs/testweb/testweb.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
因为log4j的位置放在的不是默认的路径下，所以需要在web.xml中配置监听：
<!-- log4j 配置文件的位置-->
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:config/props/log4j.properties</param-value>
</context-param> <listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
web.xml配置spring和springMVC：
<!-- 添加Spring监听 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/spring/spring-mybatis.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- Spring&mvc -->
<servlet>
<servlet-name>springMvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/spring/spring-mvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springMvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> <!-- 编码过滤器 -->
<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-</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
简单书写代码进行测试：
这里跑项目配合本地tomcat打包有点问题，直接使用jetty插件跑的：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin> <!-- jetty 插件 -->
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.3..M1</version>
</plugin>
