/与/*的区别：

/可以拦截到/login等，但拦截不到/login.jsp.而/*所有路径都可以拦截到

applicationContext.xml

在WEB-INF下创建spring-servlet.xml文件（请求相关的配置）

创建java文件夹，设置为resources root.创建

com.mmall.controller

com.mmall.dao

com.mmall.model

com.mmall.service

com.mmall.util

 

spring-servlet.xml内容

 

<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
    <context:annotation-config />
    <!-- 启动注解驱动的spring mvc 功能 -->
    <mvc:annotation-driven/>
    <context:component-scan base-package="com.mmall.controller"/>
    <context:component-scan base-package="com.mmall.service"/>

    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>
    <bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
    <bean id="jsonView" class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

在WEB-INF下创建views文件夹

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>
        <setting name="safeRowBoundsEnabled" value="true"/>
        <setting name="cacheEnabled" value="false" />
        <setting name="useGeneratedKeys" value="true" />
    </settings>
    </configuration>

 

logback对比log4j的优点

执行更快

有更丰富的文档

修改配置文件后不需要重启项目

有时间要读读logback的api,出现错误信息时可以发送邮件给相关人员或记录在某个目录

 

logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="60 seconds">

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
        </encoder>
    </appender>

    <!--<appender name="permission" class="ch.qos.logback.core.rolling.RollingFileAppender">-->
        <!--<file>${catalina.home}/logs/permission.log</file>-->
        <!--<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">-->
            <!--<FileNamePattern>${catalina.home}/logs/permission.%d{yyyy-MM-dd}.log.gz</FileNamePattern>-->
        <!--</rollingPolicy>-->
        <!--<layout class="ch.qos.logback.classic.PatternLayout">-->
            <!--<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>-->
        <!--</layout>-->
    <!--</appender>-->
    <!---->
    <!--<logger name="xxx" level="INFO">-->
        <!--<appender-ref ref="permission"/>-->
    <!--</logger>-->

    <!-- TRACE < DEBUG < INFO < WARN < ERROR -->
    <root level="INFO">
        <appender-ref ref="STDOUT" />
    </root>

</configuration>

 

验证：

@Controller
@RequestMapping("/test")
@Slf4j
public class TestController {

    @RequestMapping("/hello")
    @ResponseBody
    public String hello(){
        log.info("hello");
        return "hello, permission";
    }
}

demo:war exploded :项目运行的时候可以调试

启动项目，发现mytis木有相关文件

在dao文件夹下创建interface TestDao

resources->mapper->创建TestMapper.xml文件

<?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.mmall.dao.TestDao">

</mapper>

启动，OK
