Java框架搭建-Maven、Mybatis、Spring MVC整合搭建

Java框架搭建-Maven、Mybatis、Spring MVC整合搭建

1. 下載eclipse

到網站下載 http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/marsr

選擇自己所要的版本

2. 新建Maven項目

選擇File –> New –> Maven Project

可看到下面界面

點擊Next，可看到下面界面，我們選擇maven-archetype-webapp

點擊Next，可看到。Group Id為包名，Artifact Id為項目名。這裡我們輸入Group Id=com.cjt, Artifact Id=MyMaven。

最後點擊Finish成功創建項目

3. 項目運行前准備工作

新建項目之後，可以看到錯誤，這是build path與沒有引入javaee包引起的。

1）設置build path

右鍵項目 –> Build Path --> Configure Build Path…

然後選擇Libraries

Maven默認是選擇一個Library的，這個錯誤的，我們雙擊這個來Edit。

下面界面我們選擇Alternate JRE或者Workspace default JRE。這裡我們選擇Alternate JRE。

2）引入javaee包

在pom.xml上引入javaee包

<!-- 導入java ee jar 包 -->  
    <dependency>  
        <groupId>javax</groupId>  
        <artifactId>javaee-api</artifactId>  
        <version>7.0</version>  
    </dependency>

4. 項目配置文件設置

1) 設置pom.xml

我們現在設置pom.xml，下載jar包，這個過程可能有點慢

Pom.xml:

2) 創建jdbc.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/test
username=root
password=
#定義初始連接數
initialSize=1
#定義最大連接數
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

3) log4j.properties

### set log levels ###
#log4j.rootLogger = debug , stdout , D , E
log4j.rootLogger = debug , stdout , D

### output to the console ###
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.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n

### Output to the log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

### Save exception information to separate file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/error.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = ERROR
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

4) spring-mvc.xml

上面的文件都創建在resources文件夾下

5. 數據庫代碼自動生成

1）新建表

首先，我們新建表user_t，字段如下：

2）下載包

下載包有：mybatis-3.2.6.jar、mybatis-generator-core-1.3.3.jar、mysql-connector-java-5.1.39-bin.jar

3）運行-自動生成代碼

新建一個文件夾，下面包括如下文件

generatorConfig.xml是生成代碼的xml文件，內容如下：

<?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>
<!-- 數據庫驅動-->
<classPathEntry location="mysql-connector-java-5.1.39-bin.jar"/>
<contextid="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<propertyname="suppressDate" value="true"/>
<!-- 是否去除自動生成的注釋 true：是 ： false:否-->
<propertyname="suppressAllComments" value="true"/>
</commentGenerator>
<!--數據庫鏈接URL，用戶名、密碼-->
<jdbcConnectiondriverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="">
</jdbcConnection>
<javaTypeResolver>
<propertyname="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 生成模型的包名和位置-->
<javaModelGeneratortargetPackage="com.cjt.domain" targetProject="src">
<propertyname="enableSubPackages" value="true"/>
<propertyname="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 生成映射文件的包名和位置-->
<sqlMapGeneratortargetPackage="com.cjt.mapping" targetProject="src">
<propertyname="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 生成DAO的包名和位置-->
<javaClientGeneratortype="XMLMAPPER" targetPackage="com.cjt.dao" targetProject="src">
<propertyname="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 要生成的表 tableName是數據庫中的表名或視圖名 domainObjectName是實體類名-->
<tabletableName="user_t" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>

然後我們用cmd命令進入到新建的文件夾下面，輸入：

java -jar mybatis-generator-core-1.3.3.jar -configfile generatorConfig.xml -overwrite

最後，代碼生成了。

備注：代碼自動生成這裡通過命令行的方式，讀者也可以通過eclipse的插件方式生成。

6. 代碼開始

新建包，如下： （箭頭的都是上面自動生成的代碼）

IUserService.java

public interface IUserService {

    public User getUserById(int id);
    
}

UserServiceImpl.java

@Service
public class UserServiceImpl implements IUserService {

@Autowired
private IUserDao userDao;

public UserServiceImpl() {
System.out.println("UserServiceImpl");
}

public User getUserById(int id) {
return userDao.selectByPrimaryKey(id);
}

}

UserController.java

@Controller
@RequestMapping("/user")
public class UserController {

public UserController() {
System.out.println("UserController");
}

@Resource
private IUserService userService;

@RequestMapping("/showUser")
public String toIndex(HttpServletRequest request,Model model) {
System.out.println("UserController showUser");
int id = Integer.parseInt(request.getParameter("id"));
User user= userService.getUserById(id);
model.addAttribute("user", user);
return "showUser";
}

}

在WEB-INF下新建一個目錄jsp，下面新建文件showUser.jsp

showUser.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" import="java.util.*,com.cjt.domain.*"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
${user.userName}
</body>
</html>

最後，附上web.xml

<?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"

    </filter>

    <listener>  
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>  
    </listener>  
  
    <!-- Spring MVC servlet -->

        </init-param>  
        <load-on-startup>1</load-on-startup>  
        <async-supported>true</async-supported>  
    </servlet>  
    <servlet-mapping>  
        <servlet-name>SpringMVC</servlet-name>  
        <!-- 此處可以可以配置成*.do，對應struts的後綴習慣 -->  
        <url-pattern>/</url-pattern>  
    </servlet-mapping>  
    <welcome-file-list>  
        <welcome-file>/index.jsp</welcome-file>
