LibrarySystem图书管理系统(二)

第一步:添加数据库配置文件

jdbc.properties

# 数据库驱动
jdbc.driver=com.mysql.jdbc.Driver

# 数据库地址
jdbc.url=jdbc:mysql://localhost:3306/library?useUnicode=true&characterEncoding=UTF-8

# 用户名
jdbc.username=root

# 密码
jdbc.password=root

# 初始化连接
initialSize=0

# 最大连接数量
maxActive=20

# 最大空闲连接
maxIdle=20

# 最小空闲连接
minIdle=1

# 超时等待时间
maxWait=60000


第二步:添加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>
    <!-- 配置全局属性 -->
    <settings>
        <!-- 使用jdbc的getGeneratedKeys获取主键 -->
        <setting name="useGeneratedKeys" value="true"/>

        <!-- 使用别名替换列名, 默认ture -->
        <setting name="useColumnLabel" value="true"/>

        <!-- 开启驼峰命名转换 -->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>
</configuration>


第三步:添加Spring配置文件

在resources/spring目录下新建二个文件:

│   └── spring
│       ├── spring-mybatis.xml
│       ├── spring-service.xml
│       └── spring-mvc.xml

spring-mvc.xml

                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

    <!-- 视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/WEB-INF/views/"/>
        <!-- 后缀 -->
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

        <!-- 开启Druid的监控统计功能 -->
        <property name="filters" value="stat"/>
    </bean>

    <!-- 3.配置Mybatis的SqlSessionFactory对象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 配置MyBatis全局配置文件 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>

        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- 开启事务控制的注解支持 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>

第四步:添加logback配置文件

logback配置比log4j要简单点,功能类似

├── resources
│   ├── logback.xml

在resources文件夹下新建文件:logback.xml

<?xml version="1.0" encoding="UTF-8" ?>
<configuration debug="true">
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>
  <!--开启debug日志模式,在控制台打印日志-->
  <root level="debug">
    <appender-ref ref="STDOUT" />
  </root>
</configuration>


第五步:配置web.xml

web.xml

<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" metadata-complete="true">
  <display-name>Archetype Created Web Application</display-name>

  <!-- 配置DispatcherServlet -->
  <servlet>
    <servlet-name>seckill-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 配置springMVC需要加载的配置文件
        spring-dao.xml,spring-service.xml,spring-web.xml
        Mybatis - > spring -> springmvc
     -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/spring-*.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
  </servlet>
  <servlet-mapping>
    <servlet-name>seckill-dispatcher</servlet-name>
    <!-- 默认匹配所有的请求 -->
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- 处理中文乱码 -->
  <filter>
    <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>
