maven+SSM+shiro+junit+jetty+log4j环境配置的最佳实践

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
