1、創建maven項目（maven的下載和具體的配置省略）
2、pom.xml
<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.bob.ssm</groupId> <artifactId>zjj</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>zjj Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- Spring版本號 --> <spring.version>4.3.8.RELEASE</spring.version> </properties> <dependencies> <!-- Spring相關包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</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-aop</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-webmvc</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-tx</artifactId> <version>${spring.version}</version> </dependency> <!-- AOP相關包 --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.0</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.0</version> </dependency> <!-- MyBatis相關包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.0</version> </dependency> <!-- MySQL相關包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.26</version> </dependency> <!-- 數據庫連接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.20</version> </dependency> <!-- Spring集成MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.3</version> </dependency> <!-- JSP標准標簽庫 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志相關包 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.21</version> </dependency> <!-- 單元測試相關包 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <finalName>zjj</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.7.0</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
上述兩部完成后，項目結構如下圖：
如果項目中有紅叉錯誤的，選中項目alt+f5更新maven項目。
3、右鍵項目build path，配置server runtime,如下圖：
server Library中tomcat8.5的具體添加忽略。
此時項目結構如下圖所示：多了兩個資源包以及server runtime
4、右鍵項目，屬性，查看項目信息，如下圖：
Dynamic web module是2.3，我們要使用tomcat8.5，需要改為3.1
在workspace中修改項目.settings目錄下的文件，如下圖：
修改為：
<?xml version="1.0" encoding="UTF-8"?> <faceted-project> <fixed facet="wst.jsdt.web"/> <installed facet="java" version="1.8"/> <installed facet="jst.web" version="3.1"/> <installed facet="wst.jsdt.web" version="1.0"/> </faceted-project>
5、web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> <!-- 解決post亂碼 --> <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> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置Spring環境 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring內存溢出監聽器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- 配置SpringMVC環境 --> <servlet> <servlet-name>springMVC</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> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> </web-app>
6、下圖中所示配置文件分別為：
log4j.properties:
#USE THIS SETTING FOR OUTPUT MYBATIS`s SQL ON THE CONSOLE
log4j.rootLogger=DEBUG, Console
#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
mybatis-config.xml:

7、WEB-INF下頁面如下
error.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!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>主頁</title> </head> <body> <h3>我是錯誤頁面</h3> ${ex.message } </body> </html>
index.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>主頁</title> </head> <body> <h3>歡迎，${user.username }</h3> </body> </html>
login.jsp:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!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>登錄</title> </head> <body> <form action="${pageContext.request.contextPath }/user/login.action" method="post"> <label>賬號：</label> <input type="text" id="txtUsername" name="username" placeholder="請輸入賬號" /><br/> <label>密碼：</label> <input type="password" id="txtPassword" name="password" placeholder="請輸入密碼" /><br/> <input type="submit" value="提交" /> <input type="reset" value="重置" /> </form> </body> </html>
8、添加如下測試代碼
UserDao.java:
package com.bob.zjj.dao; import org.springframework.stereotype.Repository; import com.bob.zjj.domain.User; @Repository public interface UserDao { public abstract User findByUsername(String username); }
UserMapper.xml:
<?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.bob.zjj.dao.UserDao">
<select id="findByUsername" parameterType="string" resultType="User">
SELECT * FROM user WHERE username=#{username}
</select>
</mapper>
User.java:
package com.bob.zjj.domain; import java.util.Date; public class User { private Integer id; private String username;// 用戶姓名 private String sex;// 性別 private Date birthday;// 生日 private String address;// 地址 private String password; public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } //構造方法 public User() { super(); } public User(Integer id, String username, String sex, Date birthday, String address) { super(); this.id = id; this.username = username; this.sex = sex; this.birthday = birthday; this.address = address; } // getter/setter 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 getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public Date getBirthday() { return birthday; } public void setBirthday(Date birthday) { this.birthday = birthday; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } @Override public String toString() { return "User [id=" + id + ", username=" + username + ", sex=" + sex + ", birthday=" + birthday + ", address=" + address + ", password=" + password + "]"; } }
UserControler.java:
package com.bob.zjj.web; import javax.annotation.Resource; import javax.servlet.http.HttpSession; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.servlet.ModelAndView; import com.bob.zjj.dao.UserDao; import com.bob.zjj.domain.User; /*@RestController(value = "/user")*/ @Controller @RequestMapping(value = "/user") public class UserController { @Resource private UserDao userDao; @RequestMapping("/view") public String view() { return "login"; } @RequestMapping("/indexview") public String index() { return "index"; } @RequestMapping(value = "/login", method = RequestMethod.POST) public ModelAndView login(User model, HttpSession session) { User user = userDao.findByUsername(model.getUsername()); if (user == null || !user.getPassword().equals(model.getPassword())) { return new ModelAndView("redirect:view.action"); } else { session.setAttribute("user", user); ModelAndView mav = new ModelAndView(); mav.setViewName("index"); return mav; } } }
9、右鍵項目，run as maven build...，輸入tomcat:run
10、訪問http://localhost:8080/zjj/user/view.action
