Maven + Spring + Spring MVC +Hibernate
首先
選擇Maven--》Maven Project
點選Next
點選Next
選中如圖所示，點選Next
將Group Id ，Artifact Id 填入Package可以手動清空（我填的Group Id：com.ssh02 ， Artifact Id：ssh02）；然後點選finish。、
剛建好的工程目錄如下圖：
這時候右擊專案名，選擇Build Path--》Configure Build Path
選中JRE System Library[J2EE 1.5]點選Remove，然後再點選Order and Export ，勾選Maven Dependencies
點選Apply 然後點選ok。工程目錄結構變成如下圖
右擊專案名，選擇Properties--》Project Facets
取消勾選Dynamic Web Module ， java 改為1.8，點選右上角Runtimes 勾選tomcat 9.0（我用的是9.0） 。還是右擊專案名，選擇Properties--》Project Facets
此時 Dynamic Web Module版本變成了3.0，勾選它，然後會出現Further configuration avalilable
點選Further configuration avalilable，輸入如下圖
點選ok，Apply ，ok；工程目錄結構如下
整個工程版本，以及目錄檔案已經完全弄好，接著配置pom檔案，程式碼如下
<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.ssh02</groupId> <artifactId>ssh02</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>ssh Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <spring.version>4.3.5.RELEASE</spring.version> <hibernate.version>4.2.4.Final</hibernate.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernate.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-c3p0</artifactId> <version>${hibernate.version}</version> </dependency> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.2.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.40</version> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.2</version> </dependency> </dependencies> <build> <finalName>ssh02</finalName> </build> </project>

jsp程式碼不貼了（我懶了）
執行截圖
第一次寫，有不足的地方請大家加以糾正。
