eclipse mavne 搭建ssm框架
阿新 • • 發佈：2018-12-10
搭建java專案有疑惑的可以移步看看這個
這是新建的一個空專案
1.首先開啟 pom.xml 匯入ssm的jar包
<properties> <!-- spring版本號 --> <spring-version>4.3.18.RELEASE</spring-version> <!-- mybatis版本號 --> <mybatis-version>3.4.2</mybatis-version> </properties> <dependencies> <!-- spring基礎包 --> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring-version}</version> </dependency> <!-- spring面向切面程式設計 --> <!-- https://mvnrepository.com/artifact/org.springframework/spring-aspects --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.13</version> </dependency> <!--spring jdbc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.0.0.RELEASE</version> </dependency> <!--spring單元測試--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring-version}</version> <scope>test</scope> </dependency> <!-- mysql驅動 --> <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>6.0.6</version> </dependency> <!-- mybatis --> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis-version}</version> </dependency> <!-- mybatis整合spring的適配包 --> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.1</version> </dependency> <!-- 逆向工程 --> <!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core --> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.5</version> </dependency> <!-- 資料庫連線池 --> <!-- https://mvnrepository.com/artifact/c3p0/c3p0 --> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1</version> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet/servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <scope>provided</scope> </dependency> <!-- https://mvnrepository.com/artifact/jstl/jstl --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- https://mvnrepository.com/artifact/junit/junit --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- 分頁外掛 --> <!-- https://mvnrepository.com/artifact/com.github.pagehelper/pagehelper --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>5.0.0</version> </dependency> <!-- 返回 json 字串 --> <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.5</version> </dependency> <!-- JSR303資料校驗 --> <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-validator --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>5.4.1.Final</version> </dependency> <dependency> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.4.3</version> </dependency> <!-- 日誌管理 --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.3</version> </dependency> </dependencies>
這是ssm需要的jar包，在我的機器上沒有出現jar包衝突的問題，如果你出現了jar包衝突的問題，去本地的mavne倉庫，把這個jar包刪掉，重新下載一份，然後 update maven（如果還沒有解決的話，自行百度吧，jar包衝突煩人得很）
下載好之後，應該是這個樣子的
Maven Dependenices下面有好多jar包
2.在 src/main/resources/ 新建一個 jdbc連線資訊
右擊 resources --> new --> other 搜尋 file
輸入名字：jdbc.properties
jdbc.driverClass = com.mysql.cj.jdbc.Driver jdbc.jdbcUrl = jdbc:mysql://localhost:3306/o2o_school?serverTimezone=GMT&characterEncoding=utf8 jdbc.user = root jdbc.password = root
這些個人配置資訊是需要根據自己的電腦配置填寫的
3.依舊在這個目錄下 新建一個 mybatis-config.xml
這次搜尋xml 就好了
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <!-- 獲取資料庫自增主鍵值 --> <setting name="useGeneratedKeys" value="true"></setting> <!-- 使用列標籤替換列別名 預設值為true--> <setting name="useColumnLabel" value="true"></setting> <!-- 開啟駝峰命名規則 Table(create_time)-> Entity(createTime) --> <setting name="mapUnderscoreToCamelCase" value="true"></setting> </settings> </configuration>
4.然後在 src/main/resources/ 下面新建一個 spring.xml
右擊 resources --> new --> other 搜尋 spring
輸入 spring.xml 然後確認就好了
開啟 spring.xml,然後點選 Namespaces 有對號的打一下對號，匯入名稱空間,然後點選 source返回
3.配置spring.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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
<!-- 定義需要掃描的包 下面的base-package 的值是需要根據自己的包名修改的-->
<context:component-scan base-package="cn.junhui">
<!-- 除了controller不掃描(web), 其他的都掃描 -->
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
<!--匯入資料庫配置檔案 -->
<context:property-placeholder
location="classpath:jdbc.properties" />
<!-- 配置資料來源 -->
<bean id="pooledDataSource"
class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
<property name="driverClass" value="{jdbc.driverClass}"></property>
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<!-- 配置和mybatis整合 -->
<bean id="sqlSessionFactory"
class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 指定mybatis全域性配置檔案的位置 -->
<property name="configLocation"
value="classpath:mybatis-config.xml"></property>
<property name="dataSource" ref="pooledDataSource"></property>
<!-- 指定mybatis的mapper檔案的位置 -->
<property name="mapperLocations"
value="classpath:mapper/*.xml"></property>
<!--掃描entity包 使用別名 -->
<property name="typeAliasesPackage" value="cn.junhui.entity"></property>
</bean>
<!-- 配置掃描器，將mybatis介面的實現加入到ioc容器中去 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactory" value="sqlSessionFactory"></property>
<!--給出需要掃描的dao介面包 -->
<property name="basePackage" value="cn.junhui.dao"></property>
</bean>
<!-- 配置批量操作的sqlSession -->
<bean id="sqlSession"
class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg name="sqlSessionFactory"
ref="sqlSessionFactory"></constructor-arg>
<constructor-arg name="exectorType" value="BATCH"></constructor-arg>
</bean>
<!-- 配置service層 -->
<!--配置事務控制層 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 設定資料來源 -->
<property name="dataSource" ref="pooledDataSource"></property>
</bean>
</beans>
5.根據4的步驟新建一個springmvc.xml的配置檔案
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd">
<!-- 預設springmvc配置檔案 -->
<context:component-scan base-package="cn.junhui"
use-default-filters="false">
<!-- 只掃描controller -->
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
<!-- 檢視解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<mvc:view-controller path="/login_page"
view-name="login" />
<!-- 兩個標準配置 -->
<!-- 將springmvc不能處理的請求（靜態資源）交給tomcat -->
<mvc:default-servlet-handler />
<!-- 能支援springmvc更高階的一些功能，jsr303校驗，ajax，對映動態請求 -->
<mvc:annotation-driven />
</beans>
6.編寫 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"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<!-- 配置spring -->
<!-- needed for ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml</param-value>
</context-param>
<!-- Bootstraps the root web application context before servlet initialization -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置springmvc -->
<!-- The front controller of this Spring Web application, responsible for
handling all application requests -->
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Map all requests to the DispatcherServlet for handling -->
<servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 3.字元編碼過濾器 一定要放在所有過濾器之前 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 使用rest風格的url 將頁面普通的post請求轉化為delete或者put請求 -->
<filter>
<filter-name>HiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HiddenHttpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- ajax直接傳送put請求 -->
<filter>
<filter-name>HttpPutFormContentFilter</filter-name>
<filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HttpPutFormContentFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>到此為止,基本就搭建結束了，最後寫一個test.jsp測試一下
