UserController
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.mote.pojo.User;
import com.mote.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
private static Logger log = LoggerFactory.getLogger(UserController.class);
@RequestMapping()
public String toPage() {
log.info("页面跳转");
return "test";
}
@RequestMapping(value = "/getUser")
@ResponseBody
public User getUser(@RequestParam("id") Integer id) {
return userService.getUser(id);
}
}
UserService
import com.mote.pojo.User;
public interface UserService {
User getUser(Integer id);
}UserServiceImpl
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.mote.dao.UserDao;
import com.mote.pojo.User;
import com.mote.service.UserService;
@Service("userService")
public class UserServiceImpl implements UserService{
@Autowired
private UserDao userDao;
public User getUser(Integer id) {
return userDao.getUser(id);
}
}UserDao
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
import com.mote.pojo.User;
@Repository
public interface UserDao {
User getUser(@Param("id")Integer id);
}User
public class User {
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
四：Spring配置文件
在 src/main/resources 目录下新建properties文件【jdbc.properties】
jdbc.username=root
jdbc.password=123456
jdbc.url=jdbc:mysql://114.215.83.3:3306/bison
jdbc.driver=com.mysql.cj.jdbc.Driver在 src/main/resources 目录下新建spring配置文件【applicationContext.xml】
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
<!-- 包扫描 -->
<context:component-scan base-package="com.mote.*" />
<!-- 加载jdbc.properties文件 -->
<context:property-placeholder location="classpath:jdbc.properties" />
<!-- 配置数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<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>
</beans>五：SpringMvc配置文件
在 src/main/resources 目录下新建springmvc配置文件【springmvc-servlet.xml】
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans" 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-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 注解驱动 -->
<mvc:annotation-driven />
<!-- 配置视图解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>六：配置mybatis相关文件
在 src/main/resources 目录下创建文件夹mybatis，mybatis文件夹下面创建文件夹mappers，分别用来存放mybatis配置文件和mapper文件
1：在 src/main/resources/mybatis/mappers 目录下新建mapper文件 【UserMapper.xml】
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD iBatis Mapper 3.0 //EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.mote.dao.UserDao">
<select id="getUser" resultType="com.mote.pojo.User">
SELECT username,password FROM acl_user WHERE user_id = #{id}
</select>
</mapper>2：在 src/main/resources/mybatis 目录下新建mybatis配置文件 【mybatis-config.xml】
<?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>
<settings>
<!-- 开启驼峰命名规则 -->
<setting name="mapUnderscoreToCamelCase" value="true" />
<!-- 开启打印sql -->
<setting name="logImpl" value="STDOUT_LOGGING" />
</settings>
</configuration>3：在 src/main/resources 目录下新建spring整合mybatis配置文件【applicationContext-mybatis.xml】
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- 配置sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 定义数据源 -->
<property name="dataSource" ref="dataSource" />
<!-- mybatis全局配置文件 -->
<property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />
<!-- 扫描所有mapper.xml -->
<property name="mapperLocations" value="classpath:mybatis/mappers/**/*.xml" />
<!-- 配置别名 -->
<property name="typeAliasesPackage" value="com.mote.pojo" />
</bean>
<!-- 定义mapper接口扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.mote.dao"></property>
</bean>
</beans>七：日志实现
在 src/main/resources 目录下创建logback日志文件【logback.xml】
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE xml>
<configuration scan="true" scanPeriod="1800 seconds"
debug="false">
<!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径 -->
<property name="LOG_HOME" value="${catalina.base}/logs/" />
<!-- 控制台输出 -->
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- 设置编码和输出格式 -->
<encoder>
<charset>UTF-8</charset>
<pattern>%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{50} -
%msg%n
</pattern>
</encoder>
</appender>
<!-- 文件输出:按照每天生成日志文件 -->
<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<!-- 设置编码和输出格式 -->
<encoder charset="UTF-8">
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符 -->
<pattern>%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{50} -
%msg%n
</pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!--日志文件输出的文件名 -->
<FileNamePattern>logFile.%d{yyyy-MM-dd}.log</FileNamePattern>
<MaxHistory>30</MaxHistory>
</rollingPolicy>
<!--日志文件最大的大小 -->
<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>10MB</MaxFileSize>
</triggeringPolicy>
</appender>
<logger name="com.mote.dao" level="DEBUG"/><!-- 打印sql语句 -->
<!-- 日志输出级别 -->
<root level="INFO">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
</configuration>
八：web配置文件 web.xml
在webapp目录下创建文件夹WEB-INF,在文件夹下创建web配置文件【web.xml】
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<!-- 配置字符集 -->
<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>
<!-- springmvc前端控制器 -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 容器启动的时候加载dispatcher -->
<load-on-startup>1</load-on-startup>
<init-param>
<!-- 加载配置文件 -->
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc-servlet.xml,classpath:applicationContext*.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<!-- 设置拦截路径：/ 拦截所有请求(包括静态资源) *.do 拦截.do结尾的请求 -->
