这期内容当中小编将会给大家带来有关SpringBoot整合Activiti7的实现，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。
1.使用IDEA创建SpringBoot项目
在工程的pom.xml文件中引入相关的依赖，具体依赖如下所示
<?xml version="1.0" encoding="UTF-8"?> <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 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>activiti</artifactId> <version>0.0.1-SNAPSHOT</version> <name>activiti</name> <description>Demo project for Spring Boot</description> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter</artifactId> <version>7.0.0.Beta2</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.5</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.27</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2.application.yml文件配置
为了能够实现Activiti7生成的表放到Mysql数据库中，需要在配置文件application.yml中添加相关的配置
server: port: 8085 spring: application: name: spring-activiti datasource: url: jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT&nullCatalogMeansCurrent=true username: root password: 123456 driver-class-name: com.mysql.jdbc.Driver activiti: #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 db-history-used: true #记录历史等级 可配置的历史级别有none, activity, audit, full history-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.添加SpringSecurity安全框架整合配置
Activiti7与SpringBoot整合后，默认情况下，集成了SpringSecurity安全框架，这样我们就要去准备SpringSecurity整合进来的相关用户权限配置信息
1）添加SecurityUtil类
为了能够快速实现SpringSecurity安全框架的配置，所添加的一个组件。
@Component
public class SecurityUtil {
private Logger logger = LoggerFactory.getLogger(SecurityUtil.class);
@Autowired
@Qualifier("myUserDetailsService")
private UserDetailsService userDetailsService;
public void logInAs(String username) {
UserDetails user = userDetailsService.loadUserByUsername(username);
if (user == null) {
throw new IllegalStateException("User " + username + " doesn't exist, please provide a valid user");
}
logger.info("> Logged in as: " + username);
SecurityContextHolder.setContext(new SecurityContextImpl(new Authentication() {
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return user.getAuthorities();
}
@Override
public Object getCredentials() {
return user.getPassword();
}
@Override
public Object getDetails() {
return user;
}
@Override
public Object getPrincipal() {
return user;
}
@Override
public boolean isAuthenticated() {
return true;
}
@Override
public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
}
@Override
public String getName() {
return user.getUsername();
}
}));
org.activiti.engine.impl.identity.Authentication.setAuthenticatedUserId(username);
}
}这个类可以从Activiti7官方提供的Example中找到。
2）添加DemoApplicationConfig类
它的作用是为了实现SpringSecurity框架的用户权限的配置，这样我们就可以在系统中使用用户权限信息
@Configuration
public class DemoApplicationConfiguration {
private Logger logger = LoggerFactory.getLogger(DemoApplicationConfiguration.class);
@Bean
public UserDetailsService myUserDetailsService() {
InMemoryUserDetailsManager inMemoryUserDetailsManager = new InMemoryUserDetailsManager();
String[][] usersGroupsAndRoles = {
{"salaboy", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
{"ryandawsonuk", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
{"erdemedeiros", "password", "ROLE_ACTIVITI_USER", "GROUP_activitiTeam"},
{"other", "password", "ROLE_ACTIVITI_USER", "GROUP_otherTeam"},
{"system", "password", "ROLE_ACTIVITI_USER"},
{"admin", "password", "ROLE_ACTIVITI_ADMIN"},
};
for (String[] user : usersGroupsAndRoles) {
List<String> authoritiesStrings = Arrays.asList(Arrays.copyOfRange(user, 2, user.length));
logger.info("> Registering new user: " + user[0] + " with the following Authorities[" + authoritiesStrings + "]");
inMemoryUserDetailsManager.createUser(new User(user[0], passwordEncoder().encode(user[1]),
authoritiesStrings.stream().map(s -> new SimpleGrantedAuthority(s)).collect(Collectors.toList())));
}
return inMemoryUserDetailsManager;
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}4）创建测试类
@SpringBootTest
@Slf4j
class ActivitiApplicationTests {
@Autowired
private ProcessEngine processEngine;
/**
* 流程定义的部署
*/
@Test
public void createDeploy() {
RepositoryService repositoryService = processEngine.getRepositoryService();
Deployment deployment = repositoryService.createDeployment()
.addClasspathResource("diagram/holiday.bpmn")//添加bpmn资源
.addClasspathResource("diagram/holiday.png")
.name("请假申请单流程")
.deploy();
log.info("流程部署id:" + deployment.getName());
log.info("流程部署名称:" + deployment.getId());
}
}运行结果：
遇到的问题：
1）历史表默认不会生成，需在application.yml中配置
spring: activiti: #检测历史表是否存在 db-history-used: true #记录历史等级 可配置的历史级别有none, activity, audit, full history-level: full
