本来我是想买块肉的，但是现在我只能买块豆腐。

1. pom.xml

引入最新版本 activiti-spring-boot-starter依赖和spring-boot-starter-security。

<dependency><groupId>org.activiti</groupId><artifactId>activiti-spring-boot-starter</artifactId><version>7.1.0.M6</version>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId><version>2.2.0.RELEASE</version>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.2.0</version>
</dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope>
</dependency>
<dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional>
</dependency>
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope>
</dependency>

2. application.yml

spring:datasource:url: jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8&serverTimezone=GMTusername: rootpassword: root123driver-class-name: com.mysql.cj.jdbc.Driveractiviti:#1.flase： 默认值。activiti在启动时，会对比数据库表中保存的版本，如果没有表或者版本不匹配，将抛出异常#2.true： activiti会对数据库中所有表进行更新操作。如果表不存在，则自动创建#3.create_drop： 在activiti启动时创建表，在关闭时删除表（必须手动关闭引擎，才能删除表）#4.drop-create： 在activiti启动时删除原来的旧表，然后在创建新表（不需要手动关闭引擎）database-schema-update: true#检测历史表是否存在 activiti7默认没有开启数据库历史记录 启动数据库历史记录db-history-used: true#记录历史等级 可配置的历史级别有none, activity, audit, fullhistory-level: full#校验流程文件，默认校验resources下的processes文件夹里的流程文件check-process-definitions: false

3. database

-- 用户表，用于登录和Spring Security集成, 密码: 123456
CREATE TABLE `tb_user` (`id` int(11) NOT NULL AUTO_INCREMENT,`age` int(40) DEFAULT NULL,`username` varchar(100) DEFAULT NULL,`password` varchar(100) DEFAULT NULL,`email` varchar(100) DEFAULT NULL,`gender` int(40) DEFAULT NULL,`role` varchar(100) DEFAULT NULL,`rolegroup` varchar(100) DEFAULT NULL,PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT;INSERT INTO `tb_user` VALUES (1, 20, 'jack', '$2a$10$9FIX76XUZgIyiOTjy5iswe9fJrWuaxAwTLsJb0QFJAcu5OqTb/TJS', '123@123', 1, 'ADMIN', 'activiti_user');
INSERT INTO `tb_user` VALUES (2, 25, 'rose', '$2a$10$9FIX76XUZgIyiOTjy5iswe9fJrWuaxAwTLsJb0QFJAcu5OqTb/TJS', '234@234', 2, 'ADMIN', 'activiti_user');
INSERT INTO `tb_user` VALUES (3, 22, 'tom', '$2a$10$9FIX76XUZgIyiOTjy5iswe9fJrWuaxAwTLsJb0QFJAcu5OqTb/TJS', '345@35', 1, 'ADMIN', 'activiti_user');
INSERT INTO `tb_user` VALUES (4, 30, 'jerry', '$2a$10$9FIX76XUZgIyiOTjy5iswe9fJrWuaxAwTLsJb0QFJAcu5OqTb/TJS', '456@456', 2, 'ADMIN', 'activiti_user');-- 出差表：保存业务相关数据
CREATE TABLE `tb_evection` (`id` int(10) NOT NULL AUTO_INCREMENT,`evectionName` varchar(100) DEFAULT NULL,`num` double DEFAULT NULL,`destination` varchar(100) DEFAULT NULL,`begindate` date DEFAULT NULL,`enddate` date DEFAULT NULL,`reson` varchar(100) DEFAULT NULL,`state` int(4) DEFAULT NULL,`userid` int(20) DEFAULT NULL,PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT;

4. entity

需要实现SpringSecurity中的UserDetails接口。

@Data
public class User implements Serializable, UserDetails {private Long id;private String username;private String password;private String email;private Integer gender;private Integer age;private String role;@Overridepublic Collection<? extends GrantedAuthority> getAuthorities() {return null;}@Overridepublic String getPassword() {return password;}@Overridepublic String getUsername() {return username;}@Overridepublic boolean isAccountNonExpired() {return false;}@Overridepublic boolean isAccountNonLocked() {return false;}@Overridepublic boolean isCredentialsNonExpired() {return false;}@Overridepublic boolean isEnabled() {return false;}
}

/*** 出差申请*/
@Data
public class Evection implements Serializable {private Long id;private Long userid;/** 出差申请单名称 */private String evectionName;/** 出差天数 */private Double num;/** 预计开始时间 */private Date beginDate;/** 预计结束时间 */private Date endDate;/** 目的地 */private String destination;/** 出差事由 */private String reson;/** 0-初始录入，1-开始审批，2-审批完成 */private int state;
}

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Result {private Integer status;private String message;
}

6. main

配置Mapper扫描包。

@SpringBootApplication
@MapperScan("com.example.demo.mapper")
public class SpringbootActivitiApplication {public static void main(String[] args) {SpringApplication.run(SpringbootActivitiApplication.class, args);}
}
