IDEA	2020.1
SpringBoot	2.3.2.RELEASE
activiti-spring-boot-starter	7.1.0.M5

搭建

pom結構如下

yml配置

server:
  port: 8080

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql:///activiti?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
    username: root
    password: 123456

  # activiti配置
  activiti:
    history-level: full
    db-history-used: true
    database-schema-update: true

注意: 因為activiti整合了security,因此需要加上部分程式碼，這段程式碼可以在官方例子程式碼中找到

例子連結

@Component
public class SecurityUtil {

    private Logger logger = LoggerFactory.getLogger(SecurityUtil.class);

    @Autowired
    private UserDetailsService userDetailsService;

    public void logInAs(final String username) {

        final 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() {
            public Collection<? extends GrantedAuthority> getAuthorities() {
                return user.getAuthorities();
            }

            public Object getCredentials() {
                return user.getPassword();
            }

            public Object getDetails() {
                return user;
            }

            public Object getPrincipal() {
                return user;
            }

            public boolean isAuthenticated() {
                return true;
            }

            public void setAuthenticated(boolean b) throws IllegalArgumentException {

            }

            public String getName() {
                return user.getUsername();
            }
        }));
        org.activiti.engine.impl.identity.Authentication.setAuthenticatedUserId(username);
    }
}

到此基本算是搭建完成...

執行專案，會生成如下25張表

act_evt_log -- 估計是日誌一類的

act_ge_* -- 是儲存部署的資源的，下一篇我們就可以看到

act_hi_* --是歷史一類的，在yml裡面配置之後才會生成歷史相關的表

act_ru_* -- 不用說了，例項執行一類的相關記錄表
