篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ideax新建之后没有lib相关的知识,希望对你有一定的参考价值。
参考技术A 可以手动创建。没有lib文件夹就手动创建,然后把右边工程里的jar包都右键添加进lib。

ssm简单整合
一、整合步骤:
- 新建项目,创建一个lib目录
- 导入所有的jar包
- 新建一个config目录,设置为资源目录,用于存放配置文件
- 把所有需要的配置文件放到config目录中
- 在web.xml配置加载spring容器
- 新建所有的类和接口进行测试
二、具体实施
1.新建一个web项目,在web/WEB-INF目录下创建一个lib目录,并把此目录添加到项目依赖
点击ok之后,会再弹一个框,还是直接点击ok,
然后点击应用。
2.导入所需要的jar包
3.在根目录下新建一个目录,名为config,并把它设置为资源目录
4.编写所需的配置文件到config目录
1)编写log4j.properties文件(config目录)
### 设置当前日志级别 ### log4j.rootLogger = debug,stdout,D,E ### 输出信息到控制抬 ### log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target = System.out log4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n ### 输出DEBUG 级别以上的日志到=E://logs/log.log ### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = E://logs/log.log log4j.appender.D.Append = true log4j.appender.D.Threshold = DEBUG log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n ### 输出ERROR 级别以上的日志到=E://logs/error.log ### log4j.appender.E = org.apache.log4j.DailyRollingFileAppender log4j.appender.E.File =E://logs/error.log log4j.appender.E.Append = true log4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayout log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n
2)编写db.properties文件(config目录)
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8 jdbc.username=root jdbc.password=root
3)新建一个mybatis包,编写SqlMapConfig.xml文件
<?xml version="1.0" encoding="uTF-8" ?> <!-- mybatis核心配置 --> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <!-- 配置信息 --> <configuration></configuration>
4)新建一个spring包,编写applicationContext-dao.xml文件
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd "> <!-- 配置数据源dataSource --> <!-- 加载配置文件 --> <context:property-placeholder location="classpath:db.properties"/> <!-- 数据库连接池 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driver}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <property name="maxActive" value="10"/> <property name="maxIdle" value="5"/> </bean> <!-- 配置sqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 配置数据源 --> <property name="dataSource" ref="dataSource"/> <!-- 加载mybatis的配置文件 --> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"/> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.ssm.mapper"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> </beans>
5)编写springmvc.xml文件(spring目录)
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd "> <!--包扫描controller--> <context:component-scan base-package="com.ssm.controller"/> <!--配置注解处理器映射器和适配器--> <mvc:annotation-driven></mvc:annotation-driven> </beans>
6)编写applicationContext-service.xml文件(spring目录)
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd "> <!-- 包扫描--> <context:component-scan base-package="com.ssm.service"></context:component-scan> </beans>
7)编写applicationContext-transaction.xml文件(spring目录)
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd "> <!-- 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"/> </beans>
5.在web.xml配置加载spring容器
<?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"> <filter> <filter-name>charsetEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>CharsetEncoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>charsetEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--加载配置文件--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/springmvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
6.新建所有的类和接口
1)UserController
package com.ssm.controller; import com.ssm.entity.User; import com.ssm.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.transaction.annotation.Transactional; import org.springframework.web.bind.annotation.RequestMapping; @Controller @Transactional public class UserController { @Autowired private UserService service; @RequestMapping("/add.do") public String add(User user){ try{ service.add(user); return "success.html"; }catch(Exception e){ e.printStackTrace(); return "error.html"; } } }
2)UserService
package com.ssm.service; import com.ssm.entity.User; public interface UserService { void add(User user); }
3)UserServiceImpl
package com.ssm.service; import com.ssm.entity.User; import com.ssm.mapper.UserMapper; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; @Service public class UserServiceImpl implements UserService{ @Autowired private UserMapper mapper; @Override public void add(User user) { mapper.add(user); } }
4)User
package com.ssm.entity; import lombok.*; @Setter @Getter @ToString @AllArgsConstructor @NoArgsConstructor public class User { private int id; private String username; private String password; private String phone; }
5)UserMapper
package com.ssm.mapper; import com.ssm.entity.User; public interface UserMapper { void add(User user); }
6)UserMapper.xml(与UserMapper同包)
<?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.ssm.mapper.UserMapper"> <insert id="add" parameterType="com.ssm.entity.User"> insert into user values(1,#{username},#{password},#{phone}) </insert> </mapper>
7)index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>用户首页</title> </head> <body> <form action="add.do" method="post"> <p>用户名:<input type="text" name="username"></p> <p>密码:<input type="password" name="password"></p> <p>手机号:<input type="text" name="phone"></p> <p><input type="submit" value="注册"></p> </form> </body> </html>
8)success.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
添加成功
</body>
</html>
9)error.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
添加失败
</body>
</html>
运行测试,当添加成功会跳转到成功界面,添加失败会跳转到失败界面。
