1. spring整合activiti
1.1 依赖导入
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.4.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.12</log4j.version> <java.version>1.8</java.version> </properties> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</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.activiti.cloud</groupId> <artifactId>activiti-cloud-services-api</artifactId> <version>7.0.0.Beta1</version> </dependency> <!--activiti常规依赖--> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-engine</artifactId> <version>7.0.0.Beta1</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-bpmn-model</artifactId> <version>7.0.0.Beta1</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-bpmn-converter</artifactId> <version>7.0.0.Beta1</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-json-converter</artifactId> <version>7.0.0.Beta1</version> </dependency> <!--activiti和Spring整合依赖--> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring</artifactId> <version>7.0.0.Beta1</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>5.1.38</version> </dependency> <!--单测依赖--> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>5.0.7.RELEASE</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!--数据源--> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <!-- https://mvnrepository.com/artifact/commons-io/commons-io --> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency>
1.2 创建配置文件activiti-spring.xml
<!--数据源--> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/activiti-y2170"/> <property name="username" value="root"/> <property name="password" value="123"/> </bean> <!--配置ProcessEngineConfiguration--> <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration"> <!--数据源--> <property name="dataSource" ref="dataSource"/> <!--配置事务--> <property name="transactionManager" ref="transactionManager"/> <!--数据生成策略 true false create drop-create --> <property name="databaseSchemaUpdate" value="true"/> </bean> <!--配置ProcessEngine--> <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean"> <property name="processEngineConfiguration" ref="processEngineConfiguration"/> </bean> <!--配置RepositoryService--> <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService"/> <!--配置RuntimeService--> <bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService"/> <!--配置TaskService--> <bean id="taskService" factory-bean="processEngine" factory-method="getTaskService"/> <!--配置HistoryService--> <bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService"/> <!--配置事务管理器--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean>
1.3 如果依赖中有log4j依赖需要创建log4j配置文件
# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE debug info warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE
# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
1.4 编写测试代码 部署流程
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:activiti-spring.xml") public class ActivitiSpringTest { @Resource private RepositoryService repositoryService; @Resource private RuntimeService runtimeService; //测试流程部署 @Test public void deployment(){ repositoryService.createDeployment() .addClasspathResource("medical/medical.bpmn") .name("测试Spring流程部署") .deploy(); } }
1.5 查看数据库
2. springboot整合activiti
2.1 导入依赖
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.4.RELEASE</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <java.version>1.8</java.version> </properties> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</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>5.1.38</version> </dependency>
2.2 编写配置文件application.xml
spring: datasource: url: jdbc:mysql://localhost:3306/activiti-y2170?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT username : root password : 123 driver-class-name: com.mysql.jdbc.Driver activiti: db-history-used: true
2.3 定义流程
2.4 添加工具类DemoApplicationConfiguration
@Configuration @EnableWebSecurity public class DemoApplicationConfiguration extends WebSecurityConfigurerAdapter { private Logger logger = LoggerFactory.getLogger(DemoApplicationConfiguration.class); @Override @Autowired public void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(myUserDetailsService()); } @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"}, {"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; } @Override protected void configure(HttpSecurity http) throws Exception { http .csrf().disable() .authorizeRequests() .anyRequest() .authenticated() .and() .httpBasic(); } @Bean public PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } }
工具类SecurityUtil
@Component public class SecurityUtil { @Autowired 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"); } 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); } }
2.4 编写启动类 当启动类启动时流程自动部署
@SpringBootApplication public class StartActiviti { public static void main(String[] args) { SpringApplication.run(StartActiviti.class,args); } }
2.5 编写测试代码 查看流程定义
@RestController @RequestMapping("/activiti") public class ActivitiSpringBootTest { @Resource private ProcessRuntime processRuntime; @Resource private TaskRuntime taskRuntime; @Resource private SecurityUtil securityUtil; //查看流程定义 @RequestMapping("/getProcess") public void getProcess(){ //查询所有流程定义信息 Page<ProcessDefinition> processDefinitionPage = processRuntime.processDefinitions(Pageable.of(0, 10)); System.out.println("当前流程定义的数量："+processDefinitionPage.getTotalItems()); //获取流程信息 for (ProcessDefinition processDefinition:processDefinitionPage.getContent()) { System.out.println("流程定义信息"+processDefinition); } }
2.6 访问页面
2.7 查看控制台
2.8 启动流程实例
/** * 启动流程示例 */ @RequestMapping("/startInstance") public void startInstance(){ ProcessInstance instance = processRuntime.start(ProcessPayloadBuilder.start().withProcessDefinitionKey("demo").build()); System.out.println(instance.getId()); }
2.9 访问页面 后查看数据库
2.10 获取任务 拾取任务并执行
/** * 获取任务，拾取任务，并且执行 */ @RequestMapping("/getTask") public void getTask(){ securityUtil.logInAs("salaboy"); //指定组内任务人 Page<Task> tasks = taskRuntime.tasks(Pageable.of(0, 10)); if(tasks.getTotalItems()>0){ for (Task task:tasks.getContent()) { System.out.println("任务名称："+task.getName()); //拾取任务 taskRuntime.claim(TaskPayloadBuilder.claim().withTaskId(task.getId()).build()); //执行任务 taskRuntime.complete(TaskPayloadBuilder.complete().withTaskId(task.getId()).build()); } } }
