【ssm】springmvc-spring-mybatis框架的搭建

1.创建maven项目

    1.1 创建的是一个web项目 必须要添加web.xml文件

web.xml is missing and <failOnMissingWebXml> is set to true

   1.2 在src目录下创建一个WEB-INF的文件夹。创建web.xml文件

   <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	id="WebApp_ID" version="3.0">

	<display-name>ssm-jia</display-name>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</welcome-file>
		<welcome-file>default.html</welcome-file>
		<welcome-file>default.htm</welcome-file>
		<welcome-file>default.jsp</welcome-file>
	</welcome-file-list>
	
</web-app>

  1.3 添加项目pom 依赖jar

以上就是基本常用的jar 

  1.4 添加tomcat插件

<!-- 添加tomcat的插件 -->
	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.tomcat.maven</groupId>
				<artifactId>tomcat7-maven-plugin</artifactId>
				<configuration>
					<port>8088</port>
					<path>/</path>
				</configuration>
			</plugin>
		</plugins>
	</build>

 1.5 在web.xml中添加初始化spring容器的配置

<!-- 初始化spring容器 -->
	<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>

1.6 在web.xml文件中添加解决post乱码的类

<!-- 解决post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>

1.7 在web.xml中配置<!-- springmvc的前端控制器 -->

<!-- springmvc的前端控制器 -->
	<servlet>
		<servlet-name>monitor</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation， 
		springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>monitor</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	<servlet>
		<servlet-name>monitor</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>monitor</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

1.8 在src/main/respurce 中创建spring properties mybatis文件夹

  1.8.1 配置properties中文件

    创建db.properties 

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://xxxx:3308/ssm-jia?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

   创建log4j.properties

log4j.rootLogger=INFO,CONSOLE,DayRollingFile

#console
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.Threshold=INFO
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d - %c -%-4r [%t] %-5p %x - %m%n

# dayrollingfile
log4j.appender.DayRollingFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DayRollingFile.file=C:/cxydLogs/log_
log4j.appender.DayRollingFile.DatePattern=yyyyMMdd'.log'
log4j.appender.DayRollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.DayRollingFile.layout.ConversionPattern=/n/n[%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n

 1.8.2 spring文件夹下

  创建applicationContext-dao.xml applicationContext-service.xml applicationContext-trans.xml spring-mvc.xml

   1.8.2.1applicationContext-dao.xml

1.9mybatis中添加SqlMapConfig.xml

		"http://mybatis.org/dtd/mybatis-3-config.dtd">

	    <package name="hbsi.yfzx.pojo"/>
	</typeAliases>
		<!-- 配置分页插件 -->
	<plugins>
		<plugin interceptor="com.github.pagehelper.PageHelper">
			<!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库 -->

		</plugin>
	</plugins>
</configuration>

-------------------------到此为止 ssm配置完毕，但是还存在一个跨域问题 我们需要在配置一下。

package hbsi.yfzx.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
 * 解决SSM跨域问题
 * @author jia
 *
 */
public class SimpleCORSFilter implements Filter {
    private boolean isCross = false;

    @Override
    public void destroy() {
        isCross = false;
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        if (isCross) {
            HttpServletRequest httpServletRequest = (HttpServletRequest) request;
            HttpServletResponse httpServletResponse = (HttpServletResponse) response;
            System.out.println("拦截请求: " + httpServletRequest.getServletPath());
            httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
            httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
            httpServletResponse.setHeader("Access-Control-Max-Age", "0");
            httpServletResponse.setHeader("Access-Control-Allow-Headers",
                    "Origin, No-Cache, X-Requested-With, If-Modified-Since, Pragma, Last-Modified, Cache-Control, Expires, Content-Type, X-E4M-With,userId,token");
            httpServletResponse.setHeader("Access-Control-Allow-Credentials", "true");
            httpServletResponse.setHeader("XDomainRequestAllowed", "1");
        }
        chain.doFilter(request, response);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        String isCrossStr = filterConfig.getInitParameter("IsCross");
        isCross = isCrossStr.equals("true") ? true : false;
        System.out.println(isCrossStr);
    }



}

 在web.xml中添加

<!-- 跨域请求 -->
	<filter>
		<filter-name>SimpleCORSFilter</filter-name>
		<filter-class>hbsi.yfzx.filter.SimpleCORSFilter</filter-class>
		<init-param>
			<param-name>IsCross</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>SimpleCORSFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

配置完毕

温馨提示，我选择的ssm版本较高 只能在tomcat8上运行 tomcat7上是用不了的。
