Maven build SpringMVC+Mybatis+freemarker project detailed explanation

Others 2020-10-26 15:36:10 views: null

1. Create a new maven project, select maven-archetype-webapp, and click next


2, where the Group Id is the big project of the above mentioned id , ArifactId is the project Id . It is like a large project with many small projects. At this point, our project has taken shape, as shown below :


3. Improve the project


First of all, complete the directory and add an important sourceFolder. This is not a simple Floder. These folders will participate in the compilation. Add src/main/java, src/test/resources, src/test/java directories. Let the directory become a standard maven structure. As shown below:



Let the project’s JDK use the local jdk;
let the project’s character set be UTF-8;
change the project’s directory order;


4. Turn the project into a web project

Right-click on the project, select properties, select Project Facets, and check Dynamic Web Module


At this point, we see that there is an additional WebContent directory in the directory. Because of the use of maven to build, the web directory is src/main/webapp. Copy the content under WebContent to src/main/webapp and delete the WebContent directory.

Next, you need to configure the release directory of the web project, which is the Deployment Assembly , as shown in the figure :

Since there is no need to publish the test and the WebContent directory is gone, all three items are deleted. And add the src/main/webapp directory, and Maven Dependenices, as shown below after completion :


Therefore, our project is completely a web project .


5 , modified pom.xml add corresponding packet-dependent

6. Use Generator to automatically generate Mybatis related table information

Automatically generate the Model , Mapping , and Dao files of the table and import them into the src/main/ Java package of the project .


6.1 Add database information configuration file applicationContext.properties 

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/frameworker?useUnicode=true&characterEncoding=utf-8
jdbc_username=root
jdbc_password=123%aa



#=======================#
# 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 Add log4j information configuration file log4j.properties 

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

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender

7.1 Introduce Spring and configure related properties

Create a spring configuration file in src/main/resources , here spring.xml is created , and the information is as follows: 


<?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"></context:property-placeholder>

<!--自动扫描含有@Service将其注入为bean-->
<context:component-scan base-package="com.himal"/>

	
</beans>



7.2 Configure Mybatis related information

The following are mybatis configuration information: the 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" xmlns:tx="http://www.springframework.org/schema/tx"

    </property>
  </bean>
     
    <!-- mybatis文件配置，扫描所有mapper文件 -->
      <bean id="sqlSessionFactory"
          class="org.mybatis.spring.SqlSessionFactoryBean">
          <property name="dataSource" ref="dataSource" />
          <!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->
          <property name="mapperLocations" value="classpath:com/himal/dao/mapper/interfaces/*.xml" /><!-- configLocation为mybatis属性 mapperLocations为所有mapper-->
       </bean>
       
   <!-- spring与mybatis整合配置，扫描所有dao -->
   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.himal.dao.mapper.interfaces" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
	</bean>
  <!-- 配置事务管理器 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>
	
</beans>


7.3 New UserService class and implementation class

interface: 

package com.himal.service.interfaces;

import com.himal.dao.mapper.bo.Member;

public interface UserService {

    int insert(Member record);
}


Implementation class 


package com.himal.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.himal.dao.mapper.bo.Member;
import com.himal.dao.mapper.interfaces.MemberMapper;
import com.himal.service.interfaces.UserService;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private MemberMapper memberMapper;
    @Override
    public int insert(Member record) {
        
        memberMapper.insert(record);
        return 0;
    }

}



7.4 Test Spring and Mybatis configuration

  Write the test class in src/test/java to check whether the data can be read out. If it can read out, it proves that the Spring+Mybatis integration is successful.



package com.himal.test;

import java.util.Date;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.himal.dao.mapper.bo.Member;
import com.himal.service.interfaces.UserService;



@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:applicationContext.xml"})
public class TestUserService   {
    
    @Autowired
    private UserService userService;
    
    @Test
    public void testInsert(){
        Member record = new Member();
        record.setBirthday(new Date());
        record.setId(2l);
        record.setCreateDate(new Date());
        record.setModifyDate(new Date());
        int insert = userService.insert(record );
        System.out.println(insert);
    }
}



The test is successful, indicating that the spring + mybatis configuration is successful


8.Introduce SpringMVC

8.1 Configure SpringMVC configuration information

SpringMVC configuration information includes control layer Controller of bean management view like configuration and control layers, the following is a spring-mvc.xml Information:



<?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"

	</bean>

</beans>




9. Configure freemarker

1 Create a new AppFreemarkerView class in com.himal.frame.implementation.view


package com.himal.frame.implementation.view;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.web.servlet.view.freemarker.FreeMarkerView;

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