通過idea建立Maven專案整合Spring+spring mvc+mybatis

寫這篇文章是為了整理一下idea下整合maven專案的步驟,也為了以後讓室友們參考

建立專案

File→new→project

 

           

 

然後就不斷next直到專案面板出來

設定資料夾

     
 

注意:這裡我個人習慣,在java下還建了ssm資料夾,然後再controll...資料夾,建議跟我一樣,不然你後面配置檔案需要更改

 

   

將專案資料夾設定成這個樣子

配置檔案

  • 先修改pom.xml匯入專案所需依賴
<?xml version="1.0" encoding="UTF-8"?>

注意:如果出現提示,按這兩個圖選擇,才能匯入依賴

 

   

 

   

 

這是匯入成功後的

 

   
  • 修改WEB-INF資料夾下的web.xml
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <!-- 設定Spring容器載入配置檔案的路徑 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-mybatis.xml</param-value>
    </context-param>




    <!--解決POST亂碼問題-->
    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

            <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>
    <!-- Spring監聽器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 防止Spring記憶體溢位監聽器 -->

        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

  

因為還沒有設定springmvc.xml,所以會報錯沒關係

  • 在resources資料夾下新建jdbc.properties log4.properties spring-mvc.xml spring-mybatis.xml
    程式碼如下
    jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8

jdbc.username=root

jdbc.password=root
#定義初始連線數
initialSize=0  
#定義最大連線數
maxActive=20  
#定義最大空閒
maxIdle=20  
#定義最小空閒
minIdle=1  
#定義最長等待時間
maxWait=60000  

 

log4.properties

log4j.rootLogger=INFO,Console,File  

#控制檯日誌
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n  

#普通檔案日誌
log4j.appender.File=org.apache.log4j.RollingFileAppender  
log4j.appender.File.File=logs/ssm.log  
log4j.appender.File.MaxFileSize=10MB  
#輸出日誌,如果換成DEBUG表示輸出DEBUG以上級別日誌
log4j.appender.File.Threshold=ALL  
log4j.appender.File.layout=org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n  

 

spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>

    <!--避免IE執行AJAX時,下載JSON檔案的現象 -->
    <bean id="mappingJacksonHttpMessageConverter"
          class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>
    <!-- 啟動SpringMVC的註解功能,完成請求和註解POJO的對映 -->
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="prefix" value="/WEB-INF/page/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

 

靜態檔案例如css、js存放在static下(靜態資源只放開這個資料夾的訪問)
預設頁面存放路徑在WEB-INF資料夾下的page資料夾下,沒有自己新建
spring-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                        http://www.springframework.org/schema/tx
                        http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 元件掃描和自動裝配 -->
    <context:component-scan base-package="ssm"/>

    <!-- 載入屬性配置檔案 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>


    <!-- 配置資料來源 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>


    <!-- spring和MyBatis完美整合,不需要mybatis的配置對映檔案 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 自動掃描mapping.xml檔案 -->
        <property name="mapperLocations" value="classpath*:mapper/*.xml"></property>
    </bean>


    <!-- DAO介面所在包名,Spring會自動查詢其下的類 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="ssm.dao"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>

    <!-- (事務管理)transaction manager, use JtaTransactionManager for global tx -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- (事務管理)transaction manager, use JtaTransactionManager for global tx -->
    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

 

配置檔案基本就做好了,現在的資料夾是這個樣子的

 

   

現在就可以配置tomcat試著跑一遍了

   

 

           

然後執行就可以了

 

   

執行結果

   

為了方便專案對資料庫表的使用,我們使用MyBatis Generator自動生成程式碼

在resources下建立generatorConfig.xml檔案

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration PUBLIC
        "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
<generatorConfiguration>

    <!--資料庫驅動jar包的真實路徑 -->
    <classPathEntry
            location="D:\dataSourceDriver\mysql-connector-java-5.1.47.jar"/>

    <context id="context" targetRuntime="MyBatis3">
        <!-- 是否去除自動生成的註釋 true:是 : false:否 -->
        <commentGenerator>
            <property name="suppressAllComments" value="false"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <!--資料庫連線的資訊:驅動類、連線地址、使用者名稱、密碼 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/test"
                        userId="root"
                        password="root"/>
        <!-- 預設false,把JDBC DECIMAL 和 NUMERIC 型別解析為 Integer,為 true時把JDBC DECIMAL 和
            NUMERIC 型別解析為java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!--指定包名生成實體類 以及生成的地址 (可以自定義地址,如果路徑不存在會自動建立) -->
        <javaModelGenerator targetPackage="ssm.model" targetProject=".\src\main\java">
            <!-- enableSubPackages:是否讓schema作為包的字尾 -->
            <property name="enableSubPackages" value="false"/>
            <!-- 從資料庫返回的值被清理前後的空格 -->
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- !!!! Mapper XML Configurations !!!! -->
        <sqlMapGenerator targetPackage="mapper" targetProject="F:\ideaProject\MavenTest\src\main\resources">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- !!!! Mapper Interface Configurations !!!! -->
        <javaClientGenerator targetPackage="ssm.dao" targetProject=".\src\main\java"
                             type="XMLMAPPER">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!-- 指定資料庫表 -->
        <!-- tableName是你要生成的表名 -->
        <table schema="test" tableName="admin"
               enableCountByExample="false" enableDeleteByExample="false"
               enableSelectByExample="false" enableUpdateByExample="false"/>
    </context>
</generatorConfiguration>

 

這裡得注意
<classPathEntry
location="D:\dataSourceDriver\mysql-connector-java-5.1.47.jar"/>
這裡寫你自己電腦硬碟上的包的路徑,

<sqlMapGenerator targetPackage="mapper" targetProject="F:\ideaProject\MavenTest\src\main\resources">
<property name="enableSubPackages" value="false"/>
</sqlMapGenerator>
這裡寫你專案所在工作目錄,設定mapper.xml生成檔案位置

  • 在pom.xml中加入
<plugins>
          <plugin>
              <groupId>org.mybatis.generator</groupId>
              <artifactId>mybatis-generator-maven-plugin</artifactId>
              <version>1.3.7</version>
              <configuration>
                  <verbose>true</verbose>
                  <overwrite>true</overwrite>
              </configuration>
          </plugin>
      </plugins>

 

   
  • 點選右邊的


       

    右鍵


       
    正常情況應該生成成功,如果失敗根據情況修改
  • 這時候我們的專案環境已經全部完成


       
  • 可以寫程式碼實現功能增刪改查了,這裡使用顯示功能
  1. 在AdminMapper中增加方法
    <select id="AdminList" resultMap="BaseResultMap">
    select * from admin
    </select>

     


       

2.在dao層寫相應方法
List<Admin> AdminList();

   


3.在service層寫相應方法
先在service資料夾下建立AdminService介面,然後寫上方法
List<Admin> AdminList();
4.在impl層實現

   

 

@Service("AdminService")
public class AdminServiceimpl implements AdminService {
    @Autowired
    private AdminMapper adminMapper;
    @Override
    public List<Admin> AdminList() {
        return adminMapper.AdminList();
    }
}

 

5.在controller層寫方法

@Controller
@RequestMapping("Admin")
public class AdminController {
    @Autowired
    private AdminService adminService;
    @RequestMapping("show")
    public String show(Model model){
        List<Admin> list=adminService.AdminList();
        model.addAttribute("list",list);
        return "showAdmin";
    }
}

 

然後在page資料夾下新建showAdmin.jsp
先引入

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

 


然後主要程式碼

<c:forEach items="${list}" var="item">
<tr>
<td height="25" >${item.id}</td>
<td >${item.username}</td>
<td >${item.password}</td>
</tr>

</c:forEach>

 

   

顯示結果
