自搭建项目笔记Spring+Struts2+Hibernate《一》

SSHM 
 
 
 
 
SSHM
一：
1、建数据库
2、建maven项目
3、添加web.xml：新建一个web项目，默认生成web.xml复制过来 再删除web项目。
4、基本ssh框架pom.xml配置
    
<properties>
     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
     <spring.version>4.2.4.RELEASE</spring.version>
     <struts2.version>2.3.15.1</struts2.version>
    <Hibernate .version>4.3.11.Final</Hibernate .version>
</properties>
 
   <!--  struts2依赖 -->
    <dependency >
       <groupId >org.apache.struts </groupId>
       <artifactId >struts2-core </artifactId>
       <version >${struts2.version} </version>
  </dependency >
  
 
<!-- 添加Log4J依赖 -->
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.16</version>
</dependency>

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.6.1</version>
</dependency>

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-nop</artifactId>
<version>1.6.4</version>
</dependency>

添加Log4J（日志）、SSH依赖。
 
Javassist是一个开源的分析、编辑和创建Java字节码的类库
 
二：maven webproject 整合struts2
1、web.xml 加入中心拦截器配置
    
编辑web应用的web.xml配置文件，配置struts2的核心Filter，这个可以从Struts2官网(http://struts.apache.org/development/2.x/docs/webxml.html)找到示例。
2前面我们提到Maven构建web项目时资源文件存放在src/main/resources目录下，但是Struts2的配置文件struts.xml默认要放在类路径下，也就是src下。
这个位置可以修改（http://www.cnblogs.com/surge/p/3581954.html），就是在web.xml中的struts2的<filter>里加入以下内容：
<init-param>   
   <param-name>config</param-name>   
   <param-value>../../resources/struts.xml</param-value>   
</init-param> 
 
配置完成后web.xml内容如下：
  1. <!DOCTYPE web-app PUBLIC  
  2.  "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"  
  3.  "http://java.sun.com/dtd/web-app_2_3.dtd" >  
  4.   
  5. <web-app>  
  6.   <display-name></display-name>  
  7.     
  8.       
  9.     <filter>  
  10.         <filter-name>struts2</filter-name>  
  11.         <filter-class>  
  12.             org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter  
  13.         </filter-class>
    • <init-param>  
    •         <param-name>config</param-name>  
    •         <param-value>../../resources/struts.xml</param-value>  
    •     </init-param>  
  15.   
  16.     </filter>  
  17.     <filter-mapping>  
  18.         <filter-name>struts2</filter-name>  
  19.         <url-pattern>/*</url-pattern>  
  20.     </filter-mapping>  
  21.   
  22.     <welcome-file-list>  
  23.         <welcome-file>login.jsp</welcome-file>  
  24.     </welcome-file-list>  
  25. </web-app>  
 
2、加入log4j.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//Apache//DTD Log4j 1.2//EN"
"http://logging.apache.org/log4j/docs/api/org/apache/log4j/xml/log4j.dtd">
<log4j:configuration>
<appender class="org.apache.log4j.ConsoleAppender" name="RootConsoleAppender">
<param name="Threshold" value="debug" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n" />
</layout>
</appender>

<category name="com.fengshu.limanman.winssage">
<priority value="debug" />
</category>

<category name="org.springframework">
<priority value="warn" />
</category>

<category name="org.hibernate">
<priority value="warn" />
</category>
<category name="org.dbunit">
<priority value="warn" />
</category>

<category name="com.mchange.v2">
<priority value="warn" />
</category>
<category name="org.apache">
<priority value="warn" />
</category>
<category name="org.logicalcobwebs">
<priority value="warn" />
</category>
<category name="com.opensymphony">
<priority value="warn" />
</category>

<root>
<level value="info" />
<appender-ref ref="RootConsoleAppender" />
</root>

</log4j:configuration>
 
3、引入struts2.xml 
<?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE struts PUBLIC  
  "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"  
   "http://struts.apache.org/dtds/struts-2.3.dtd">  
<struts>  
         <!-- 所有匹配*.do的请求都由struts2处理 -->
        <constant name="struts.action.extension" value="do" /> 
        <constant name="struts.i18n.reload" value="false" />  
        <constant name="struts.devMode" value="false" />  
        <include file="struts-default.xml" />  
        <package name="default" extends="struts-default" namespace="/">  
               <action name="login" class="com.carson.demo.action.UserAction" method="login">                                                                        <result name="success">index.jsp</result>  
                    <result name="login">login.jsp</result>
                </action>
         </package>  
</struts>  
 
 
 
（暂时注释掉pom.xml中的struts2-spring-plugin

因为还没有整合spring，如果加入struts2-spring-plugin将会报空指针异常，整合spring后需要加入此jar包，下面将不再提及。）

使用struts2注解在pom.xml里配置：

<dependency>
      <groupId>org.apache.struts</groupId>
      <artifactId>struts2-convention-plugin</artifactId>
      <version>${struts2.version}</version>
</dependency>

<dependency>
     <groupId>org.apache.struts</groupId>
     <artifactId>struts2-json-plugin</artifactId>
     <version>${struts2.version}</version>
</dependency>

4、配置jetty运行环境：在pom.xml中加入jetty插件，并且配置根目录目
<build>
        <plugins>
            <!-- 配置加入jetty服务器，开发时我们一般使用 jetty服务器 -->
            <plugin>
                <groupId> org.mortbay.jetty</groupId >
                <artifactId> jetty-maven-plugin</artifactId >
                <configuration>
                    <!-- 设置扫描target/classes内部文件变化时间间隔 -->
                    <scanIntervalSeconds> 2</ scanIntervalSeconds>
                    <webApp>
                        <contextPath> /*</ contextPath>
                    </webApp>
                </configuration>
            </plugin>
            <!-- compiler插件, 设定JDK版本 -->
            <plugin>
                <groupId> org.apache.maven.plugins</groupId >
                <artifactId> maven-compiler-plugin</artifactId>
                <version> 3.0</ version>
                <configuration>
                    <source> 1.8</ source>
                    <target> 1.8</ target>
                    <showWarnings> true</ showWarnings>
                </configuration>
            </plugin>
 
            <!-- war打包插件, 设定war包名称不带版本号 -->
            <plugin>
                <groupId> org.apache.maven.plugins</groupId >
                <artifactId> maven-war-plugin</artifactId>
                <version> 2.3</ version>
                <configuration>
                    <warName> winssage</ warName>
                </configuration>
            </plugin>
            <!-- eclipse插件, 设定 wtp版本 -->
            <plugin>
                <groupId> org.apache.maven.plugins</groupId >
                <artifactId> maven-eclipse-plugin</artifactId>
                <version> 2.9</ version>
                <configuration>
                    <downloadSources> true</ downloadSources>
                    <downloadJavadocs> false</ downloadJavadocs>
                    <wtpversion> 2.0</ wtpversion>
                </configuration>
            </plugin>
            <plugin>
                <groupId> org.apache.maven.plugins</groupId >
                <artifactId> maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id> install</ id>
                        <phase> install</ phase>
                        <goals>
                            <goal> sources</ goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <!-- 用于支持跨模块加载配置文件 -->
            <plugin>
                <groupId> org.apache.maven.plugins</groupId >
                <artifactId> maven-resources-plugin</artifactId>
                <version> 2.5</ version>
                <configuration>
                    <encoding> UTF-8</ encoding>
                    <nonFilteredFileExtensions>
                        <nonFilteredFileExtension> dll</ nonFilteredFileExtension>
                        <nonFilteredFileExtension> so</ nonFilteredFileExtension>
                    </nonFilteredFileExtensions>
                </configuration>
            </plugin>
        </plugins>
    </build >
 
 
三、整合spring
1、在pom.xml 加入spring依赖
    
<!-- 添加Spring依赖 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>${spring.version}</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
 
2、web.xml加入spring监听
 
<!-- spring路径 -->
<context-param>
    <param-name>contextConfigLocation </param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

<!-- Spring Listener -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
 
3、添加spring配置文件 applicationContext.xml 在spring里配置bean，把bean转给spring管理
<?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:jee="http://www.springframework.org/schema/jee"
        xmlns:tx="http://www.springframework.org/schema/tx"         xmlns:context="http://www.springframework.org/schema/context"
        xsi:schemaLocation="http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/jee         http://www.springframework.org/schema/jee/spring-jee-2.5.xsd http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-2.5.xsd">
 
<bean id="loginController" class="test.t1.user.action.LoginController">
</bean>
</beans>
 
Struts.xml:
<package name="test" namespace="/" extends="struts-default">
    <action name="user" class="loginController">
        <result name="success">/jsp/index.jsp</result>
    </action>
</package>
 
strust2整合spring时要在pom.xml中的加入struts2-spring-plugin，在运行项目测试

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-spring-plugin</artifactId>
    <version>${struts2.version}</version>
</dependency>
 
 

四、spring再整合hibernate 

1、在pom.xml 加入hibernate、mysql依赖

<!--添加Hibernate依赖 -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>${Hibernate.version}</version>
</dependency>
<dependency>
    <groupId>commons-dbcp</groupId>
    <artifactId>commons-dbcp</artifactId>
    <version>1.4</version>
</dependency>

<!-- 添加mysql依赖 -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.6</version>
</dependency>

2、建立Hibenate.properties 属性配置文件

3、建立spring-hibernate.xml文件

4、在web.xml 加入spring-hibernate.xml

5、在applicationContext.xml 加入Hibenate.properties 属性配置文件，并加入spring-hibernate.xml内容，并bean配置改为扫描注解文件：

 

6、写modeldaoserviceaction 并配置注解

1）用sessionFactory.getCurrentSession()遇到问题：

org.hibernate.HibernateException: Could not obtain transaction-synchronized

解决：在applicationContext.xml中配置事物：

<!-- 配置事务管理器 -->
<bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 注解方式配置事物 -->
<tx:annotation-driven transaction-manager="transactionManager" />

并在DAO实现类上标注：@Transactional

2）@Resource不能注入

原因：
<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-spring-plugin</artifactId>
    <version>${struts2.version}</version>
</dependency>
 
被注释 解除注释即可
