Maven搭建SpringMVC+Mybatis+freemarker項目詳解

1、新建一個maven project ，選中maven-archetype-webapp，點擊next

2、填寫相應信息

這裏的Group Id就是大項目的id，ArifactId就是該項目的Id。就像一個大項目中有許多小項目組成一樣。此時，我們的項目已經成型了，樣子如下圖：

3、完善項目

首先，完善目錄，增加重要的sourceFolder，這個不是簡單的Floder,這些文件夾是會參與編譯的。增加src/main/java，src/test/resources，src/test/java目錄。讓目錄變成標準的maven結構。如下圖：

讓工程的JDK用本地的jdk;

讓工程的字符集爲UTF-8;

改變工程的目錄順序；

4、將工程變成web工程

我們選擇Dynamic Web Module

此時，我們看到目錄中多了一個WebContent目錄，由於使用maven構建，web目錄是src/main/webapp,所以我們刪除WebContent目錄。接下來，要配置web項目的發佈目錄，就是Deployment Assembly，如圖：

test目錄不要發佈，WebContent目錄沒有了，所以這三項都刪掉。並且增加src/main/webapp目錄，和Maven Dependenices,完成之後如下圖：

於是，我們的工程就完全是一個web工程了。

5、修改pom.xml添加對應的包依賴

pom.xml

6、使用Generator自動生成Mybatis相關表信息

自動生成表的Model，Mapping，Dao文件，先關使用見文章 http://blog.csdn.net/fengshizty/article/details/43086833

並將其導入到項目的src/main/java包中。

其中生成的Model中如下：

6.1加入數據庫信息配置文件applicationContext.properties

# BIBD At-Tamwil : App Server
# Local Copy
# Last Update: 14 Nov 2012


#====================#
# Core Configuration #
#====================#



jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/police?useUnicode=true&characterEncoding=utf-8
jdbc_username=root
jdbc_password=root



#=======================#
# Logging Configuration #
#=======================#

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

log4j.rootLogger=debug, stdout

log4j.logger.org.apache=info
log4j.logger.org.springframework=info

6.2加入log4j信息配置文件log4j.properties

### set log levels ###
log4j.rootLogger = INFO , C , D , E 

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.Target = System.out
log4j.appender.C.layout = org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern = [police][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ../logs/springmvc-mybatis-demo.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [police][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### exception ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = ../logs/springmvc-mybatis-demo_error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [police][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

7.1引入Spring並配置相關屬性

在src/main/resources META-INF創建spring的配置文件，這裏創建了spring.xml，信息如下：

<?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:context="http://www.springframework.org/schema/context"
	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">
 
    <!-- 引入jdbc配置文件 -->
    <context:property-placeholder location="classpath:applicationContext.properties"/>
     
    <!--自動掃描含有@Service將其注入爲bean -->
	<context:component-scan base-package="com.yefan.frame.implementation.service" />
	
</beans>

7.2配置Mybatis相關信息

以下是mybatis的配置信息：spring-mybatis.xml（ps：名字可隨便起）

<?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:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-4.1.xsd 
		http://www.springframework.org/schema/tx 
		http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
		http://www.springframework.org/schema/aop 
		http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
		">
 
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" 
    destroy-method="close" >
    <property name="driverClassName">
      <value>${jdbc_driverClassName}</value>
    </property>
    <property name="url">
      <value>${jdbc_url}</value>
    </property>
    <property name="username">
      <value>${jdbc_username}</value>
    </property>
    <property name="password">
      <value>${jdbc_password}</value>
    </property>
    <!-- 連接池最大使用連接數 -->
    <property name="maxActive">
      <value>20</value>
    </property>
    <!-- 初始化連接大小 -->
    <property name="initialSize">
      <value>1</value>
    </property>
    <!-- 獲取連接最大等待時間 -->
    <property name="maxWait">
      <value>60000</value>
    </property>
    <!-- 連接池最大空閒 -->
    <property name="maxIdle">
      <value>20</value>
    </property>
    <!-- 連接池最小空閒 -->
    <property name="minIdle">
      <value>3</value>
    </property>
    <!-- 自動清除無用連接 -->
    <property name="removeAbandoned">
      <value>true</value>
    </property>
    <!-- 清除無用連接的等待時間 -->
    <property name="removeAbandonedTimeout">
      <value>180</value>
    </property>
    <!-- 連接屬性 -->
    <property name="connectionProperties">
      <value>clientEncoding=UTF-8</value>
    </property>
  </bean>
     
    <!-- mybatis文件配置，掃描所有mapper文件 -->
      <bean id="sqlSessionFactory"
          class="org.mybatis.spring.SqlSessionFactoryBean">
          <property name="dataSource" ref="dataSource" />
          <!-- 自動掃描entity目錄, 省掉Configuration.xml裏的手工配置 -->
          <property name="mapperLocations" value="classpath:META-INF/mapper/*.xml" /><!-- configLocation爲mybatis屬性 mapperLocations爲所有mapper-->
       </bean>
       
   <!-- spring與mybatis整合配置，掃描所有dao -->
   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.yefan.frame.implementation.mapper" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
	</bean>
  <!-- 配置事務管理器 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>
	
	
</beans>

7.3 新建UserService類以及實現類

public interface UserService {

intdeleteByPrimaryKey(Stringid);

int insert(User record);

int insertSelective(Userrecord);

User selectByPrimaryKey(String id);

intupdateByPrimaryKeySelective(Userrecord);

intupdateByPrimaryKey(Userrecord);

}

實現類

public class UserServiceImpl implements UserService {

	
@Autowired
	private UserMapper userMapper;
	
	@Override
	public int deleteByPrimaryKey(String id) {
		// TODO Auto-generated method stub
		return userMapper.deleteByPrimaryKey(id);
	}

	@Override
	public int insert(User record) {
		// TODO Auto-generated method stub
		return userMapper.insert(record);
	}

	@Override
	public int insertSelective(User record) {
		// TODO Auto-generated method stub
		return userMapper.insertSelective(record);
	}

	@Override
	public User selectByPrimaryKey(String id) {
		// TODO Auto-generated method stub
		return userMapper.selectByPrimaryKey(id);
	}

	@Override
	public int updateByPrimaryKeySelective(User record) {
		// TODO Auto-generated method stub
		return userMapper.updateByPrimaryKeySelective(record);
	}

	@Override
	public int updateByPrimaryKey(User record) {
		// TODO Auto-generated method stub
		return userMapper.updateByPrimaryKey(record);
	}

}

7.4 測試Spring和Mybatis配置

在src/test/java中寫測試類，檢測是否能夠讀出數據，若能讀出則證明Spring+Mybatis整合成功。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:META-INF/spring/web-context.xml" })
public class TestUserService {

	private static final Logger LOGGER = Logger
			.getLogger(TestUserService.class);

	@Autowired
	private UserService userService;

	
	@Test
	public void testQueryById1() {
		User userInfo = userService.selectByPrimaryKey("1");
		LOGGER.info(JSON.toJSON(userInfo));
	}

	@Test
	public void testQueryAll() {
		List<User> userInfos = userService.selectAll();
		LOGGER.info(JSON.toJSON(userInfos));
	}

	@Test
	public void testInsert() {
		User userInfo = new User(null, null, null, null,null);
		userInfo.setId(UUID.randomUUID().toString());
		userInfo.setName("xiaoming");
		userInfo.setUserNum("asdas2123");
		int result = userService.insertUser(userInfo);
		System.out.println(result);
	}
}

測試成功說明spring + mybatis配置成功

1這裏如果出現問題

右鍵properties

8.引入SpringMVC

8.1 配置SpringMVC配置信息

SpringMVC的配置信息主要包括控制層Controller的bean管理，視圖層和控制層配置等等，下面是spring-mvc.xml信息：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
	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/mvc 
		http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

	<!-- 自動掃描controller包下的所有類，如果@Controller注入爲bean -->
	<context:component-scan base-package="com.yefan.frame.implementation.controller" />

	<!-- 避免IE執行AJAX時,返回JSON出現下載文件 -->
	<bean id="mappingJacksonHttpMessageConverter"
		class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>text/html;charset=UTF-8</value>
			</list>
		</property>
	</bean>

	<!-- 啓動Spring MVC的註解功能，完成請求和註解POJO的映射 -->
	<bean
		class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<!-- json轉換器 -->
				<ref bean="mappingJacksonHttpMessageConverter" />
			</list>
		</property>
	</bean>



	<!-- 配置多文件上傳 -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="defaultEncoding">
			<value>UTF-8</value>
		</property>
		<property name="maxUploadSize">
			<!-- 上傳文件大小限制爲31M，31*1024*1024 -->
			<value>32505856</value>
		</property>
		<property name="maxInMemorySize">
			<value>4096</value>
		</property>
	</bean>

</beans>

9.配置freemarker

1在com.yefan.frame.implementation.view新建AppFreemarkerView類

public class AppFreemarkerView extends FreeMarkerView {
	public static final String CONTEXT_PATH = "base";
	
	@SuppressWarnings("all")
	protected void exposeHelpers(Map model, HttpServletRequest request)
			throws Exception {
		super.exposeHelpers(model, request);
		model.put(CONTEXT_PATH, request.getContextPath());
	}
}

在meta-inf/spring下新建freemarker.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" xmlns:context="http://www.springframework.org/schema/context"  
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"  
    xmlns:mvc="http://www.springframework.org/schema/mvc"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
           http://www.springframework.org/schema/beans/spring-beans-3.2.xsd  
            http://www.springframework.org/schema/context  
           http://www.springframework.org/schema/context/spring-context-3.2.xsd  
           http://www.springframework.org/schema/aop  
           http://www.springframework.org/schema/aop/spring-aop-3.2.xsd  
           http://www.springframework.org/schema/tx   
           http://www.springframework.org/schema/tx/spring-tx-3.2.xsd  
           http://www.springframework.org/schema/mvc   
           http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">   
	<!-- 向spring中注入默認註解映射處理器以及把指定控制包下面的控制層注入到spring中 -->
	<mvc:annotation-driven />
	<mvc:default-servlet-handler/>

 
    <bean id="freemarkerConfig"
		class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
		<property name="templateLoaderPath" value="/WEB-INF/freemarker/" /><!-- 將/WEB-INF/freemarker/目錄下的文件當作view -->
	</bean>

	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
		<property name="cache" value="true" />
		<property name="prefix" value="" />
		<property name="suffix" value=".ftl" />
		<property name="viewClass"
			value="com.yefan.frame.implementation.view.AppFreemarkerView" /><!-- 解決view 中base路徑問題 -->
	</bean>
	
</beans>

9．2

在meta-inf/spring下新建web-context.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"
	xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
">
	<import resource="spring.xml" />
	<import resource="spring-mybatis.xml" />
	<import resource="spring-mvc.xml" />
	<import resource="freemarker.xml" />

</beans>

10.、Web容器web.xml配置

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

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
