环境：win10+jdk8+tomcat9+Intellij IDEA
首先，作为一个喜欢偷懒的人，管理jar之类的的事情太累，所以用了Gradle项目管理器
第一步：
新建一个gradle-web项目，目录结构为
在build.gradle中添加
group ‘com.pigge‘ version ‘1.0-SNAPSHOT‘ apply plugin: ‘java‘ apply plugin: ‘war‘ apply plugin: ‘idea‘ sourceCompatibility = 1.8 repositories { mavenLocal() mavenCentral() } //让resource文件自动加载到class路径下 idea{ module{ inheritOutputDirs=true; } } dependencies { def springVersion = "4.3.8.RELEASE" testCompile group: ‘junit‘, name: ‘junit‘, version: ‘4.11‘ testCompile group: ‘junit‘, name: ‘junit‘, version: ‘4.12‘ compile("org.springframework:spring-aop:$springVersion", "org.springframework:spring-orm:$springVersion", "org.springframework:spring-jdbc:$springVersion", "org.springframework:spring-core:$springVersion", "org.springframework:spring-context:$springVersion", "org.springframework:spring-beans:$springVersion", "org.springframework:spring-tx:$springVersion", "org.springframework:spring-web:$springVersion", "org.springframework:spring-webmvc:$springVersion",) compile group: ‘mysql‘, name: ‘mysql-connector-java‘, version: ‘5.1.40‘ compile(group: ‘org.mybatis‘, name: ‘mybatis‘, version: ‘3.4.5‘,) compile group: ‘org.mybatis‘, name: ‘mybatis-spring‘, version: ‘1.3.1‘ compile group: ‘javax‘, name: ‘javaee-api‘, version: ‘7.0‘ compile group: ‘org.apache.logging.log4j‘, name: ‘log4j-api‘, version: ‘2.2‘ compile group: ‘org.apache.logging.log4j‘, name: ‘log4j-core‘, version: ‘2.2‘ compile group: ‘org.apache.logging.log4j‘, name: ‘log4j-slf4j-impl‘, version: ‘2.2‘ compile group: ‘org.apache.logging.log4j‘, name: ‘log4j-jcl‘, version: ‘2.2‘ compile group: ‘org.slf4j‘, name: ‘slf4j-api‘, version: ‘1.7.10‘ compile group: ‘org.apache.logging.log4j‘, name: ‘log4j-web‘, version: ‘2.2‘ }
在resource下新建database.properties
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/StudentMS?characterEncoding=utf8&useSSL=true jdbc.username=root jdbc.password=123456
再新建spring-config.xml
<?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:aop="http://www.springframework.org/schema/aop" 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/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!--配置Spring的扫描路径--> <context:component-scan base-package="com.pigge.controller"/> <context:component-scan base-package="com.pigge.service"/> <!--加载配置文件--> <context:property-placeholder location="classpath:database.properties"/> <!--配置springmvc解析式--> <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"/> <property name="suffix" value=".jsp"/> </bean> <!--配置数据源--> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.driver}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> </bean> <!--配置mybatis的sqlSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="mapperLocations" value="classpath:com/pigge/mapper/*.xml"/> </bean> <!--使用spring自动装配mapper类--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 注入sqlSessionFactory --> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <!-- 给出需要扫描Dao接口包 --> <property name="basePackage" value="com.pigge.mapper"/> </bean> </beans>
在修改web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <!--配置log4j2,是它可以识别${web:rootDir}--> <context-param> <param-name>log4jContextName</param-name> <param-value>star</param-value> </context-param> <!--加载spring--> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param><!--加载配置文件--> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-config.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
再在resource下新建log4j2.xml文件
<?xml version="1.0" encoding="UTF-8"?> <Configuration status="off" monitorInterval="1800"> <Appenders> <Console name="Console" target="SYSTEM_OUT"> <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/> </Console> <RollingFile name="RollingFileInfo" fileName="${web:rootDir}/WEB-INF/logs/info.log" filePattern="${web:rootDir}/WEB-INF/logs/$${date:yyyy-MM}/info-%d{yyyy-MM-dd}-%i.log"> <!--控制台只输出level及以上级别的信息（onMatch），其他的直接拒绝（onMismatch）--> <ThresholdFilter level="info" onMatch="ACCEPT" onMismatch="DENY"/> <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/> <Policies> <TimeBasedTriggeringPolicy/> <SizeBasedTriggeringPolicy size="10MB"/> </Policies> </RollingFile> </Appenders> <Loggers> <root level="info" includeLocation="true"> <appender-ref ref="Console"/> <appender-ref ref="RollingFileInfo"/> </root> </Loggers> </Configuration>
然后，在entity包下建立实体类
public class Student {
private Integer id;
private String name;
private String sex;
private LocalDate birthday;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public LocalDate getBirthday() {
return birthday;
}
public void setBirthday(LocalDate birthday) {
this.birthday = birthday;
}
@Override
public String toString() {
return "Student{" +
"id=" + id +
", name=‘" + name + ‘\‘‘ +
", sex=‘" + sex + ‘\‘‘ +
", birthday=" + birthday +
‘}‘;
}
}
在mapper包下建立StudentMapper.java(dao层，有的喜欢取名为**Dao类）
public interface StudentMapper { @Select("select * from student where id = #{id}") Student selectOne(Integer id); }
在resource文件夹下建立与mapper包相同的路径，再新建StudentMapper.xml(否则StudentMapper.java与StudentMapper.xml不在同一文件夹下，容易出错)
<?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.pigge.mapper.StudentMapper"> </mapper>
空的什么方法也没有，测试时只调用StudentMapper.java的抽象方法
在service下新建StudentService
public interface StudentService { Student selectOne(Integer id); }
再在service下的impl包新建StudentServiceImpl
@Service public class StudentServiceImpl implements StudentService { private StudentMapper studentMapper; public StudentMapper getStudentMapper() { return studentMapper; } @Autowired public void setStudentMapper(StudentMapper studentMapper) { this.studentMapper = studentMapper; } @Override public Student selectOne(Integer id) { return studentMapper.selectOne(1); } }
在controller下建立StudentController.java
@Controller public class StudentController { private StudentService studentService; @RequestMapping("show") public String show(ModelMap map,HttpServletRequest request){ map.put("student",studentService.selectOne(1)); return "success"; } public StudentService getStudentService() { return studentService; } @Autowired public void setStudentService(StudentService studentService) { this.studentService = studentService; } }
在新建一个success.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
${requestScope.student}
</body>
</html>
将项目加载到Tomcat,执行
好了，测试已经成功了
