前一段时间一直在实训，给实训单位做了一些关于工作流引擎的项目。由于老师说这部分东西不属于保密部分，所以在这里记录一下自己学习activiti的一些心得。这个系列的文章将分为四部分，用户管理、模型管理、流程管理和Activiti modeler整合四个部分。在本篇文章中，我们讲解最简单的部分，那就是系统的用户管理

一、创建Maven项目：

1、创建maven webapp类型项目









2、设置项目文件夹：

在main包下右键java新建文件夹。然后在File –Project Structure中，设置文件夹类型：
Java包：源代码
Resource包：资源文件夹
Webapp：web文件夹










最后项目文件夹目录如下图所示：



根据上述结构图，创建文件夹及相关配置文件

注：加红线部分可以不创建，在后续整合activiti modeler会用到

二、配置SpringMVC

a) 配置webapp/WEB-INF目录下的web.xml
为web.xml添加以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
<display-name>Archetype Created Web Application</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>web.root</param-value>
  </context-param>
  <!--配置springmvc DispatcherServlet-->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <!--Sources标注的文件夹下需要新建一个spring文件夹-->
      <param-name>contextConfigLocation</param-name>
      <param-value>
        classpath*:/applicationContext.xml
      </param-value>
    </init-param>

    <filter-name>springSessionRepositoryFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>
b) applicationContext.xml中配置SpringMVC Servlet相关

                     pointcut="execution(* com.adc.gim.service.impl.*.*(..))"/>
    </aop:config>
</beans>

c)配置数据库jdbc.properties，注意更改你的数据库链接、用户和密码

jdbc.url=jdbc:mysql://localhost:3306/activitimvc?characterEncoding=UTF-8&characterSetResults=UTF-8
jdbc.username=root
jdbc.password=root
jdbc.driverClassName=com.mysql.jdbc.Driver

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true
hibernate.hbm2ddl.auto = update
d) 在pom 中添加以下依赖：

三、增加实体类、控制类和工具类

1. 增加用于用户管理的用户实体类

User.java

import javax.persistence.*;
import java.io.Serializable;
import java.util.List;

/**
 * Created by YanMing on 2017/7/13.
 */
@Entity
@Table(name = "t_user")
public class User implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(updatable = false, nullable = false)
    private Long id;

    @Column(name = "username", nullable = false)
    private String username;

    @Column(name = "password", nullable = false)
    private String password;


    public User(String username, String password) {
        this.username = username;
        this.password = password;
    }
    public User(){

    }

    public Long getId() {
        return id;
    }

    public void setId(Long 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;
    }


}
2、添加控制类

LoginController.java到controller包

package com.adc.gim.controller;

import com.adc.gim.entity.User;
import com.adc.gim.service.UserService;
import com.adc.gim.utils.SpringSessionUtil;
import com.sun.org.apache.bcel.internal.generic.AALOAD;
import org.activiti.engine.IdentityService;
import org.springframework.beans.factory.annotation.Autowired;
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.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.servlet.http.HttpSession;

/**
 * @Date: 13:41 2017/6/5
 * 控制登陆、注册、主页跳转功能
 *
*/
@Controller
@RequestMapping("/")
public class LoginController {


    /**

        User tmpUser = SpringSessionUtil.getSession(session);
        if (tmpUser != null) {
            return "redirect:/loginOK";
        } else {
            return "loginPage";

    @RequestMapping(value = "/logout")
    public String logout(HttpSession session) {
        session.removeAttribute(SpringSessionUtil.USER);
        return "loginPage";
    }


}

3、添加服务类，把UserService接口和UserServiceImpl添加到service和service.impl中

UserService.java

package com.adc.gim.service;

import com.adc.gim.entity.User;

/**
 * Created by YanMing on 2017/6/6.
 */

/**
* @Autohr:YanMing
* @Description:
* @Date: 13:40 2017/6/15
*/
public interface UserService {

    User getUserById(Long id);
    User getUserByUsername(String username);
    void saveNewUser(User user);
}
UserServiceImpl.java

package com.adc.gim.service.impl;

import com.adc.gim.entity.User;
import com.adc.gim.repository.UserRepository;
import com.adc.gim.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.PreparedStatementSetter;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.jdbc.support.GeneratedKeyHolder;
import org.springframework.jdbc.support.KeyHolder;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.transaction.UserTransaction;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

/**
 * Created by YanMing on 2017/6/6.
 */
@Service
@ComponentScan(basePackages = "com.adc.gim.repository")
public class UserServiceImpl implements UserService {

    @Autowired
    private UserRepository userRepository;

    @Autowired
    private JdbcTemplate jdbcTemplate;

    /**
    * @Date: 16:56 2017/6/2
     * 根据id获取用户
    */
    public User getUserById(Long id) {
        return userRepository.findById(id);
    }

    /**
    * @Date: 16:56 2017/6/2
     * 根据用户名获取用户
    */
    public User getUserByUsername(String username) {
        return userRepository.findByUsername(username);
    }

    public void saveNewUser(User user){
        String sql4user = "insert into t_user(username,password)VALUES (?,?)";
        //String sql4group = "insert into t_user(username,password)VALUES (?,?)"
        //KeyHolder resKeyHolder = new GeneratedKeyHolder();
        jdbcTemplate.update(sql4user, new PreparedStatementSetter() {
            @Override
            public void setValues(PreparedStatement ps) throws SQLException {
                ps.setString(1,user.getUsername());
                ps.setString(2,user.getPassword());
            }
        });
        //String uid = String.valueOf(resKeyHolder.getKey().intValue());

    }

}

4、添加数据库访问类

UserRepository.java

package com.adc.gim.repository;

import com.adc.gim.entity.User;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
 * Created by YanMing on 2017/6/6.
 */
/**
* @Date: 16:13 2017/6/18
 * 实现jpaRepository<>接口
 * 访问jpa
*/
@Repository
@Transactional
public interface UserRepository extends JpaRepository<User,Long> {

    User findByUsername(String username);
    User findById(Long id);
}

5、添加通用工具，把SpringSessionUtil添加到util包中


package com.adc.gim.utils;

import com.adc.gim.entity.User;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

/**
 * Created by YanMing on 2017/6/28.
 */
public class SpringSessionUtil {

    public static final String USER = "user";

    public static void setSession(HttpSession session,  User user)
    {
        session.setAttribute(USER, user);
    }

    public static User getSession(HttpSession session) {
        Object attribute = session.getAttribute(USER);
        return attribute == null ? null : (User) attribute;
    }
}
6、在WEB-INF下的view中添加loginPage.html和index.html

loginPage.html

<!DOCTYPE html>

    <meta charset="UTF-8"/>
    <link rel="shortcut icon" href="/static/images/favicon.ico" />

            padding-top: 200px;
        }
    </style>
</head>
<body>

<div class="container" style="width: 600px">

    </div>
    <br/>

    </div>
    <br/>
    <input type="button" class="form-control btn btn-success" onclick="clickLogin()" value="登 陆"/>

    <br/><br/>
    <p style="text-align: right">还没注册？<a href="/register">快去注册</a></p>
