使用IntelliJ IDEA进行SSH整合(一)

拼搏现实的明天。 2022-03-11 09:54 853阅读 0赞

#### 最近在学习SSH框架,趁着刚学完这三个框架,已经迫不及待的进行了整合,让我们开始吧! ####

运行环境:  
IDE: IntelliJ IDEA 2018.3  
Java version: 1.8  
Java EE version:java EE 7  
Application Server: Tomcat 8.5.31  
Web Application version: 3.1  
Database: MySQL 8.0

## 第一步:创建web项目，引入jar包 ##

#### Struts2的jar包: ####

struts-2.3.24\\apps\\struts2-blank\\WEB-INF\\lib\*.jar  
asm-3.3.jar  
asm-commons-3.3.jar  
asm-tree-3.3.jar  
commons-fileupload-1.3.1.jar  
commons-io-2.2.jar  
commons-lang3-3.2.jar  
freemarker-2.3.22.jar  
javassist-3.11.0.GA.jar  
log4j-api-2.2.jar  
log4j-core-2.2.jar  
ognl-3.0.6.jar  
struts2-core-2.3.24.jar  
xwork-core-2.3.24.jar

#### Hibernate的jar包: ####

hibernate-release-5.0.7.Final\\lib\\required\*.jar  
antlr-2.7.7.jar  
dom4j-1.6.1.jar  
geronimo-jta\_1.1\_spec-1.1.1.jar  
hibernate-commons-annotations-5.0.1.Final.jar  
hibernate-core-5.0.7.Final.jar  
hibernate-jpa-2.1-api-1.0.0.Final.jar  
jandex-2.0.0.Final.jar  
javassist-3.18.1-GA.jar  
jboss-logging-3.3.0.Final.jar

#### MySQL驱动: ####

mysql-connector-java-8.0.11.jar

#### 日志记录: ####

log4j-1.2.16.jar  
slf4j-api-1.6.1.jar  
slf4j-log4j12-1.7.2.jar

#### 使用C3P0连接池： ####

c3p0-0.9.2.1.jar  
hibernate-c3p0-5.0.7.Final.jar  
mchange-commons-java-0.2.3.4.jar  
注意：Struts2和Hibernate都引入了一个相同的jar包(javassist包),删除一个.Log4j重复没事

## 第二步:引入配置文件 ##

#### Struts的配置文件 ####

##### web.xml #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 1]

##### struts.xml #####

#### Hibernate的配置文件 ####

##### hibernate.cfg.xml #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 3]  
**代码如下:**

<hibernate-configuration>
        <session-factory>
            
            <property name="hibernate.connection.driver_class">com.mysql.cj.jdbc.Driver</property>

            <property name="hibernate.format_sql">true</property>
            
            <property name="hibernate.hbm2ddl.auto">update</property>

            <property name="c3p0.max_size">20</property>
            
            <property name="c3p0.timeout">120</property>
            
            <property name="c3p0.idle_test_period">3000</property>
    
            
    
        </session-factory>
    </hibernate-configuration>

##### 映射文件: #####

**创建Customer.java实体类和Customer.hbm.xml映射文件**

##### 在hibernate.cfg.xml中引入映射文件的位置 #####

![在这里插入图片描述][20190307193012953.png]

#### Spring的配置文件 ####

##### 在src目录下创建applicationContext.xml #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 7]

##### 在web.xml中加入以下代码 #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 8]

#### 日志记录 ####

##### 在src目录下创建log4j.properties,代码如下 #####

### direct log messages to stdout ###
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.Target=System.err
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
    
    ### direct messages to file mylog.log ###
    log4j.appender.file=org.apache.log4j.FileAppender
    log4j.appender.file.File=c\:mylog.log
    log4j.appender.file.layout=org.apache.log4j.PatternLayout
    log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
    
    ### set log levels - for more verbose logging change 'info' to 'debug' ###
    # error warn info debug trace
    log4j.rootLogger= info, stdout

#### 第三步:创建包结构 ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 9]

#### 第四步:创建相关类 ####

##### 目前项目整体目录结构: #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 10]

#### 第五步:编写index.jsp ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 11]

#### 第六步：Spring整合Struts2:Action交给Spring管理。 ####

##### 编写CustomerAction类: #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 12]

##### 引入插件包 #####

###### 引入struts-spring-plugin.jar(之前引入过就不用引了) ######

![在这里插入图片描述][20190307193654336.png]

###### 在applicationContext.xml中加入如下代码: ######

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 13]

###### 在struts.xml中配置Action: ######

![在这里插入图片描述][20190307193749341.png]

#### 第七步：Service调用DAO ####

##### 将DAO交给Spring管理 #####

![在这里插入图片描述][20190307193859884.png]

##### 在Service注入DAO #####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 14]

#### 第八步：Spring整合Hibernate框架 ####

##### Spring和Hibernate整合 #####

###### 在Spring的配置文件中，引入Hibernate的配置的信息 ######

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 16]

##### 在Spring和Hibernate整合后，Spring提供了一个Hibernate的模板类简化Hibernate开发。 #####

###### 改写DAO继承HibernateDaoSupport ######

![在这里插入图片描述][20190307194153905.png]

###### 配置的时候在DAO中直接注入SessionFactory ######

![在这里插入图片描述][2019030719422235.png]

###### 在DAO中使用Hibernate的模板完成保存操作 ######

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 17]

#### 第九步：配置Spring的事务管理 ####

##### 在applicationContext.xml配置事务管理器 #####

![在这里插入图片描述][20190307194330868.png]

##### 在applicationContext.xml开启注解事务 #####

![在这里插入图片描述][20190307194339392.png]

##### 在业务层使用注解 #####

![在这里插入图片描述][20190307194346221.png]

#### 第十步：启动服务器,进入index页面 ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 18]

#### 第十一步：填入信息并提交,观察控制台与数据库变化 ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2Nzk4Mjcy_size_16_color_FFFFFF_t_70 19]

### 测试正常,整合成功! ###
