## 一、SpringMVC 开发环境搭建 ##

### 1、创建项目 permission ###

2、引入 pom.xml 依赖，并使用properties管理 version 版本

<properties>
        <springframework.version>4.3.10.RELEASE</springframework.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.7</maven.compiler.source>
        <maven.compiler.target>1.7</maven.compiler.target>
      </properties>

          <version>1.7.22</version>
        </dependency>
      </dependencies>

## 二、环境配置： ##

1、配置web.xml

配合Spring beans 配置文件路径：

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
      </context-param>

配置前端控制器：

默认指向 WEB-INF下的spring-servlet.xml文件

<servlet>
        <servlet-name>spring</servlet-name> //默认指向 spring-servlet.xml文件
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      </servlet>
      <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>

配置字符集，解决乱码问题：

<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>
        <init-param>
          <param-name>forceEncoding</param-name>
          <param-value>true</param-value>
        </init-param>
      </filter>
      <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>

2、SpringMVC 配置文件: spring-servlet.xml

引入springmvc 上下文注解配置及包扫描controller、service两个目录，并配置前端解析器

<context:annotation-config />
    
        
        <mvc:annotation-driven/>
    
    
        
        <context:component-scan base-package="com.webcode.springboot.controller" />
        <context:component-scan base-package="com.webcode.springboot.service" />
    
        <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>

3、配置 applicationContext.xml

配置DB数据库连接参数及Druid相关参数

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="ignoreUnresolvablePlaceholders" value="true"/>
            <property name="locations">
                <list>
                    <value>classpath:settings.properties</value>
                </list>
            </property>
        </bean>
    
        
    
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
            <property name="driverClassName" value="${db.driverClassName}" />
            <property name="url" value="${db.url}" />
            <property name="username" value="${db.username}" />
            <property name="password" value="${db.password}" />
            <property name="initialSize" value="3" />
            <property name="minIdle" value="3" />
            <property name="maxActive" value="20" />
            <property name="maxWait" value="60000" />
            <property name="filters" value="stat,wall" />
        </bean>

配置对应连接数据库参数文件：settings.xml

![20190928141945798.png][]

DB相关参数：

db.driverClassName=com.mysql.cj.jdbc.Driver
    db.url=jdbc:mysql://localhost:3333/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&autoReconnect=true&serverTimezone=UTC
    db.username=root
    db.password=admin

4、配置 mybatis-config.xml

applicationContext.xml 添加sqlSessionFactory配置：

mybatis-config.xml 配置：关闭缓存等

5、事务管理配置： applicationContext.xml

事务管理器：

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource" />
        </bean>
    
        <tx:annotation-driven transaction-manager="transactionManager" />

监控DB：

<bean id="stat-filter" class="com.alibaba.druid.filter.stat.StatFilter">
            <property name="slowSqlMillis" value="3000" />
            <property name="logSlowSql" value="true" />
            <property name="mergeSql" value="true" />
        </bean>
        <bean id="wall-filter" class="com.alibaba.druid.wall.WallFilter">
            <property name="dbType" value="mysql" />
        </bean>

6、配置 druid ，添加相关配置，实现 druid 进行登录认证：

<servlet>
        <servlet-name>DruidStatServlet</servlet-name>
        <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
        <init-param>
          <param-name>loginUsername</param-name>
          <param-value>druid</param-value>
        </init-param>
        <init-param>
          <param-name>loginPassword</param-name>
          <param-value>druid</param-value>
        </init-param>
      </servlet>
      <servlet-mapping>
        <servlet-name>DruidStatServlet</servlet-name>
        <url-pattern>/sys/druid/*</url-pattern>
      </servlet-mapping>
      <filter>
        <filter-name>DruidWebStatFilter</filter-name>
        <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
        <init-param>
          <param-name>exclusions</param-name>
          <param-value>*.js,*.css,*.jpg,*.png,*.ico,*.gif,/sys/druid/*</param-value>
        </init-param>
      </filter>
      <filter-mapping>
        <filter-name>DruidWebStatFilter</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>

7、配置 logback.xml 日志管理

<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>
    
        //日志级别
        
        <root level="INFO">
            <appender-ref ref="STDOUT" />
        </root>

## 三、SpringMVC开发环境验证： ##

### 1、创建接口： TestController ###

@Controller
    @RequestMapping("/test")
    @Slf4j
    public class TestController {
    
        @RequestMapping("/hello")
        @ResponseBody
        public String hello(){
    //        log.info("hello");
            System.out.println("dddddddd");
            return "hello,permission";
        }
    }

### 2、tomcat 服务配置： ###
