ssm配置清单，注意事项
- spring
- spring mvc
- mybatis
对pom.xml文件的操作
pro.xml priject中，日常会经常用到的4个子标签 dependencyManagment、dependencies、build和profiles
-
打包的设置
<packaging>war</packaging> -
构建的设置
<build> <plugins> <!-- java编译插件，指定jdk版本 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.8.0</version> <configuration> <source>1.8</source> <target>1.8</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> <!-- 配置资源打包路径 --> <resources> <resource> <!--目录--> <directory>src/main/java</directory> <!--包括--> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <!--过滤--> <filtering>true</filtering> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>true</filtering> </resource> </resources> </build> -
依赖的导入
<!-- 依赖--> <dependencies> <!-- 单元测试--> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> <!-- servlet--> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>${javax.servlet-api.version}</version> <scope>provided</scope> </dependency> <!-- jsp依赖--> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>${javax.servlet.jsp-api.version}</vers <scope>provided</scope> </dependency> <!-- jsp标准库 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <!-- myBatis--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatisSpring--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>${mybatis-spring.version}</version> </dependency> <!-- spring依赖--> <dependency> <!-- 切面编程--> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring-webmvc.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring-webmvc.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring-webmvc.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring-webmvc.version}</version> </dependency> <dependency> <!--spring表达式，可以更灵活的注入--> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${spring-webmvc.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring-webmvc.version}</version> </dependency> <dependency> <!--这个好像是事务管理--> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring-webmvc.version}</version> </dependency> <!-- springMvc依赖--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring-webmvc.version}</version> </dependency> <!-- mysql依赖--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql-connector-java.version}</versi </dependency> <!-- log4j--> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> </dependencies> -
依赖的版本配置
<!-- 依赖版本声明 project.build.sourceEncoding配置文件编码!!!一定要设置--> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spring-webmvc.version>5.2.8.RELEASE</spring-webmvc.version> <log4j.version>1.2.17</log4j.version> <mysql-connector-java.version>5.1.47</mysql-connector-java.version> <mybatis-spring.version>2.0.0</mybatis-spring.version> <mybatis.version>3.5.5</mybatis.version> <jstl.version>1.2</jstl.version> <javax.servlet-api.version>4.0.0</javax.servlet-api.version> <javax.servlet.jsp-api.version>2.3.3</javax.servlet.jsp-api.version> <junit.version>4.12</junit.version> </properties>```
到这里，已经配置好了pom文件，基本上使用没有什么问题了，否需有问题再记录
对spring mvc使用的配置
json转实体类使用RequestBody注解,实体类转json添加jackson-databind依赖
- json转实体类必须要有空构造方法,不然会报错
-
文件框架
<?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_4_0.xsd" version="4.0"> </web-app> -
配置DispatcherServlet进web.xml
<!-- 请求拦截--> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!-- 这里指向了DispatcherServlet --> <param-value>classpath:springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 拦截了所有请求--> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> -
配置springmvc-servlet.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: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/cache http://www.springframework.org/schema/cache/spring-cache.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 配置扫描的路径 --> <context:component-scan base-package="com.phcCommunity"/> <!--配置字符串http消息转换器，返回json数据，注意命名空间必须是 xmlns:mvc="http://www.springframework.org/schema/mvc" --> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes" value="application/json;charset=UTF-8"/> </bean> </mvc:message-converters> </mvc:annotation-driven> </beans> -
添加jackson依赖
<!-- 使用该依赖是需要将返回的室内类映射为json --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.6</version> </dependency>
mybatis结合使用

配置连接池
-
依赖
<dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> -
mybatis没有开发c3p0的的数据源连接，需要开发之自行实现，只需要继承UnpooledDataSourceFactory并把dataSourc 实现即可
public class C3p0DataSource extends UnpooledDataSourceFactory { public C3p0DataSource() { this.dataSource = new ComboPooledDataSource(); } } -
修改mybatis 的全局配置，主要是将数据源替换为c3p0的，添加了initialPoolSize等连接池配置，还有修改了一些property的name，在使用pooled数据源时和c3p0数据源时 property中driver，url，username名字不同
<dataSource type="com.phcCommunity.utils.C3p0DataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"/> <property name="jdbcUrl" value="jdbc:mysql://192.168.198.128:3306/mybatis?useSSL=false&useUnicode=true&characterEncoding=UTF-8"/> <property name="user" value="root"/> <property name="password" value="123456"/> <property name="initialPoolSize" value="5"/> <property name="maxPoolSize" value="100"/> <property name="minPoolSize" value="5"/> </dataSource> -
可能会警告需要log4j配置文件，创建log4j.properties文件
#将等级为DEBUG的日志信息输出到console和file这两个目的地，console和file的定义在下面的代码 log4j.rootLogger=DEBUG,console,file #控制台输出的相关设置 log4j.appender.console = org.apache.log4j.ConsoleAppender log4j.appender.console.Target = System.out log4j.appender.console.Threshold=DEBUG log4j.appender.console.layout = org.apache.log4j.PatternLayout log4j.appender.console.layout.ConversionPattern=[%p][%c]-%m%n #文件输出的相关设置 log4j.appender.file = org.apache.log4j.RollingFileAppender log4j.appender.file.File=./log/blog.txt log4j.appender.file.MaxFileSize=10mb log4j.appender.file.Threshold=DEBUG log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=[%p][%d{yy-MM-dd}][%c]%m%n #日志输出级别 log4j.logger.org.mybatis=DEBUG log4j.logger.java.sql=DEBUG log4j.logger.java.sql.Statement=DEBUG log4j.logger.java.sql.ResultSet=DEBUG log4j.logger.java.sql.PreparedStatement=DEBUG -
顺便说一下log4j的使用
private static Logger logger = Logger.getLogger("test");mybatis第三方c3p0连接池配置完成，等待使用过程技术补充
配置线程池
-
编写@EnableAsync配置类
@Configuration @EnableAsync public class AsyncConfiguration { @Bean public Executor asyncException(){ ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(2); executor.setMaxPoolSize(10); executor.setThreadNamePrefix("phc_community_task_worker-"); executor.setQueueCapacity(30); return executor; } } -
使用@Async来编写异步程序
@Async public String add() throws InterruptedException { for (int i = 0; i < 10; i++) { //暂停线程 Thread.sleep(1000); System.out.println(i); if (i == 9) { System.out.println(i); return String.valueOf(i); } } return "ghost know what this"; } -
调用@Async标记的方法来执行异步程序
taskService.add();
配置线程池完成，等待使用过程技术补充
邮件发送配置

添加依赖
<dependency> <groupId>com.github.whvcse</groupId> <artifactId>easy-captcha</artifactId> <version>1.6.2</version> </dependency> -
编写实现

配置 redis
-
添加依赖
<!-- java连接redis的包 --> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>3.3.0</version> </dependency> <!--spring整合redis的jar包--> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>2.0.8.RELEASE</version> </dependency> -
我不使用spring整合方式，直接使用jedis来对redis进行操作
-
编写配置文件
#连接池配置 maxTotal=50 maxIdle=10 #ip位置 host=192.168.198.128 #端口 port=6379 #密码 pwd=123456 #响应超时 timeout=2000 -
编写工具类
public class JedisUtils { /** * 创建一个连接池 */ private static JedisPool jedisPool; static { //读取配置文件 InputStream inputStream = JedisUtils.class.getClassLoader().getResourceAsStream("jedis.properties"); Properties properties = new Properties(); try { properties.load(inputStream); } catch (IOException e) { e.printStackTrace(); } //连接池配置 JedisPoolConfig config = new JedisPoolConfig(); config.setMaxTotal(Integer.parseInt(properties.getProperty("maxTotal"))); config.setMaxIdle(Integer.parseInt(properties.getProperty("maxIdle"))); //初始化连接池，把对应参数传递进去 jedisPool =new JedisPool(config, properties.getProperty("host"), Integer.parseInt(properties.getProperty("port")), Integer.parseInt(properties.getProperty("timeout")), properties.getProperty("pwd")); } //返回jedis对象 public static Jedis getJedis(){ return jedisPool.getResource(); } } -
调用该工具类的getJedis方法可以从连接池中获取一个jedis连接
@Test public void testJedis() { Jedis jedis = JedisUtils.getJedis(); SetParams setParams = new SetParams(); setParams.ex(60); jedis.set("hashah","axb",setParams); jedis.close(); }
