思路大致是 jetty插件 -> junit -> SpringMVC -> Spring -> Mybatis整合 -> shiro整合 -> log4j
pom中的依赖跟着思路一批一批的来
创建项目
1、eclipse中创建一个maven项目，Packing选war，
Project Facts的Dynamic Web Module改成3.1，Java改成1.8。
2、创建后用Java EE Tools -> Generate Deployment Descriptor Stub生成WEB-INF目录。
错误消除。
3、Build Path的JRE改成workspace默认。
jetty插件
4、本地仓库找到\.m2\repository\org\mortbay\jetty\jetty-maven-plugin\里面找到jar包，
提取出/src/main/resources/jetty/webdefault.xml，useFileMappedBuffer改成false，
拷贝进项目src/main/resources的jetty中，pom.xml里追加<build/>
<build>
<plugins>
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>8.1.16.v20140903</version>
<configuration>
<webDefaultXml>/src/main/resources/jetty/webdefault.xml</webDefaultXml>
<scanIntervalSeconds>2</scanIntervalSeconds>
<webApp>
<contextPath>/</contextPath>
</webApp>
<stopKey>shutdown</stopKey>
<stopPort>8085</stopPort>
</configuration>
</plugin>
</plugins>
</build>
5、eclipse -> Run创建一个External Tools，
Main选项卡中Location指向maven客户端，
Working Directory指向本项目，
Arguments填jetty:run，
Environment选项卡中追加
MAVEN_OPTS -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=8090,server=y,suspend=y
6、创建一个Remote DEBUG，端口填8090
※ 红蓝先后启动后，浏览器输入http://localhost:8080/已经能看到效果了，同时这个模式也是debug模式了
Directory: / WEB-INF/ 0 bytes 2017-7-10 16:09:14
7、想要关闭的话，创建一个External Tools即可，其中Arguments填jetty:stop，Environment中不追加参数
※ 默认端口号(8080)，DEBUG用端口号(8090)，关闭用端口号(8085)，三者最好不一致，避免不必要的麻烦。
junit
8、pom.xml中追加junit
SpringMVC
9、pom.xml中追加
spring-webmvc
servlet-api
10、web.xml中追加DispatcherServlet，顺便把编码过滤器也加了
<servlet>
<servlet-name>spring-webmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springframework/dispatcherservlet-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring-webmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<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>
11、src/main/resources的springframework中创建配置文件
dispatcherservlet-servlet.xml
<!--
以下几个第一次就可以直接配置了
命名空间：直接拷贝
注解驱动：直接拷贝
扫描controller：改包名
视图解析器：改位置
静态资源：一般需要css、js、img等
-->
<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-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
<!-- 注解驱动 -->
<mvc:annotation-driven />
<!-- 扫描controller -->
<context:component-scan base-package="io.deolin.controller" />
<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 静态资源 -->
<mvc:resources mapping="/js/**" location="/js/" />
<mvc:resources mapping="/html/**" location="/html/" />
</beans>
※ SpringMVC完成，可以写个controller测试一下
Spring
12、需要spring-context依赖，但在spring-webmvc里面已经有了，所以pom.xml不用追加了
13、src/main/resources的springframework中创建配置文件
application-context.xml
<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-2.0.xsd">
<bean class="io.deolin.util.SpringContext" />
</beans>
14、创建类io.deolin.util.SpringContext
package io.deolin.util;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;
public class SpringContext implements ApplicationContextAware {
private static ApplicationContext applicationContext;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
SpringContext.applicationContext = applicationContext;
}
public static ApplicationContext getApplicationContext() {
return applicationContext;
}
public static Object getBean(String name) throws BeansException {
try {
return applicationContext.getBean(name);
} catch (Exception e) {
throw new RuntimeException("Bean不存在！");
}
}
}
※ Spring完成，Spring上下文被映射到了工具类SpringContext，可以写个POJO，注册到application-context.xml中，测试一下
