spring-boot,mybatisplus,activiti集成

spring-boot,mybatisplus,activiti集成

這些是本身在作集成時的筆記,測試經過,activiti使用7.0版本.

0 yml配置文件中添加:

spring: 
  activiti:
    check-process-definitions: true
    #啓用做業執行器
    async-executor-activate: false
    #啓用異步執行器
    job-executor-activate: false
    database-schema-update: true
    process-definition-location-prefix: classpath:/process/
    history-level: audit
    db-history-used: true

1 添加依賴包:

<dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-spring-boot-starter</artifactId>
            <version>7.0.0.Beta2</version>
            <!-- 與MP衝突,去掉依賴 -->
            <exclusions>
                <exclusion>
                    <groupId>org.mybatis</groupId>
                    <artifactId>mybatis</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <!-- 如下兩個配置是爲了去掉serverendpoint異常 -->
        <!--去除內嵌tomcat-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>
        <!--websocket依賴包-->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-websocket</artifactId>
            <version>8.5.23</version>
        </dependency>

2 在resource目錄下添加一個目錄process,這裏是存放npmn,圖片文件的默認位置

3 啓動主類上添加排序security的參數:
@SpringBootApplication(exclude = SecurityAutoConfiguration.class)
4 添加一個SpringSecurity配置類:

@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();
    }
}

5.添加類SecurityUtil:

import java.util.Collection;

@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);
    }
}

6 添加一個bmpn文件,test.bmpn
7 測試代碼,會生成28張表格與部署工做流

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ActivitiTest {

    @Autowired
    private ProcessRuntime processRuntime;
    @Autowired
    private TaskRuntime taskRuntime;
    @Autowired
    private SecurityUtil securityUtil;

    @Test
    public void test1(){
        securityUtil.logInAs("salaboy");
        ProcessInstance pi = processRuntime.start(ProcessPayloadBuilder.start().withProcessDefinitionKey("myProcess_1").build());
        System.out.println(pi.getId());

    }

}
