sts(eclipse)+maven搭建ssm框架

Posted 2020-10-19 -lanfenglanmeng

1、创建maven项目（maven的下载和具体的配置省略）

2、pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </plugins>
    </build>
</project>

上述两部完成后，项目结构如下图：

如果项目中有红叉错误的，选中项目alt+f5更新maven项目。

3、右键项目build path，配置server runtime,如下图：

server Library中tomcat8.5的具体添加忽略。

此时项目结构如下图所示：多了两个资源包以及server runtime

 

4、右键项目，属性，查看项目信息，如下图：

Dynamic web module是2.3，我们要使用tomcat8.5，需要改为3.1

在workspace中修改项目.settings目录下的文件，如下图：

修改为：

<?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">
  <!-- 解决post乱码 -->
    <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环境 -->
    <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内存溢出监听器 -->    
    <listener>    
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>    
    </listener>

    <!-- 配置SpringMVC环境 -->
    <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、下图中所示配置文件分别为：

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

    </bean>
</beans>

 

7、WEB-INF下页面如下

 

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>主页</title>
</head>
<body>
<h3>我是错误页面</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">

</body>
</html>

<input type="submit" value="提交" />
<input type="reset" value="重置" />
</form>
</body>
</html>

 

8、添加如下测试代码

 

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;// 用户姓名
    private String sex;// 性别
    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;
    }
    //构造方法
    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、右键项目，run as maven build...，输入tomcat:run

10、访问http://localhost:8080/zjj/user/view.action
