(菜鳥來動手)SpringMVC+Spring+Mybatis整合(第三天) SSM框架整合
阿新 • • 發佈：2019-02-03
前一段寫了前2天的內容,本來想一個框架一個框架網上增.後來發現不好整... 這次參考網上的文章,一次將3個框架整合到一起.記錄下來.
大體步驟:
1.新建maven web 專案
2.引入jar包
3.寫業務程式碼
4.配置檔案
5.測試
開始:
一:
1)第一步直接上圖,new maven project
2. 這裡選擇 maven-archetype-webapp, 但是這個出來預設的是web module是2.3,jdk是1.5,貌似要使用自定義catalog才可以自己設定.
3.這個基本都是隨便寫了. artifactid 是專案名稱
4. finish後,生成目錄結構如下圖,可以看到 沒有src的路徑,
5.修改 jre lib位置,不使用預設的
6.
7. 修改後,再看目錄, 已經有src目錄了, 可能是個bug導致的.
8.到project facets, 修改jdk版本和 web module,發現報錯 cannot change version of project facet dynamic web module to 3.0
9.開啟navigator檢視,到settings資料夾下,將裡面的配置檔案中的JDK版本 1.5,改到1.7, web module 2.3 改到 3.0
10. 還要修改下web.xml 修改後如下
<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> </web-app>
第一步完成,開始第二部.
二:引入jar包
這個就比較簡單,需要的jar包,引入到pom.xml就可以了,直接貼上程式碼
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.xm</groupId> <artifactId>ssm</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>ssm Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- spring版本號 --> <spring-version>4.0.2.RELEASE</spring-version> <!-- mybatis版本號 --> <mybatis.version>3.2.6</mybatis.version> <!-- log4j日誌檔案管理包版本 --> <slf4j.version>1.7.7</slf4j.version> <log4j.version>1.2.17</log4j.version> <!-- mysql driver --> <mysql-version>5.1.27</mysql-version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring-version}</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- 匯入Mysql資料庫連結jar包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.27</version> </dependency> <!-- 匯入dbcp的jar包，用來在applicationContext.xml中配置資料庫 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <!-- Servlet --> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日誌檔案管理包 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> <finalName>ssm</finalName> </build> </project>
三:配置檔案
1.main-content.xml , 相當與 application-content.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.xsd">
<import resource="spring-mybatis.xml" />
</beans>2.spring-mybatis.xml, 用於配置 資料來源
<?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:p="http://www.springframework.org/schema/p"

xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context

<!-- 自動掃描 -->
<context:component-scan base-package="com.xm.common" />
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

<property name="url" value="jdbc:mysql://localhost:3306/test?user=root&password=123456&useUnicode=yes&characterEncoding=UTF-8" />
</bean>

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
3.spring-mvc.xml , 用於配置 springmvc
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"
default-lazy-init="true">
<!-- DispatcherServlet Context: defines this servlet's request-processing

<!-- Enables the Spring MVC @Controller programming model -->
<mvc:annotation-driven />
<context:component-scan base-package="com.xm.common.controller" />

<beans:bean

四:程式碼
model
package com.xm.common.model;
import java.io.Serializable;
public class User implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String userName;
private String password;
private Integer age;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Override
public String toString() {
return "User [id=" + id + ", userName=" + userName + ", password="
+ password + ", age=" + age + "]";
}
}
package com.xm.common.dao;
import com.xm.common.model.User;
public interface UserDao {
User selectByPrimaryKey(Integer id);
}
mapping
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.xm.common.dao.UserDao">

</mapper>service
package com.xm.common.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.xm.common.dao.UserDao;
import com.xm.common.model.User;
@Service("userService")
public class UserService {
@Autowired

public User getUserById(int userId) {
return this.userDao.selectByPrimaryKey(userId);

}controller

@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/showUser")
public String toIndex(Model model,Integer userId){
User user = this.userService.getUserById(userId);
model.addAttribute("user", user);
return "showUser";
}
}
showUser.jsp

OK. 測試成功! 初步整合完成. 後面再繼續完善.
