集成

为方便本地测试，此样例以H2作为服务数据库。

可以随时删除清空整个库，可以默认自动创建数据库表。

1.创建Maven工程

2.pom.xml配置

3.application.yaml配置

# 开发环境配置
server:
  # 服务器的HTTP端口，默认为8080
  port: 8082
  servlet:
    # 应用的访问路径
    context-path: /acti
  tomcat:
    # tomcat的URI编码
    uri-encoding: UTF-8
    # 连接数满后的排队数，默认为100
    accept-count: 1000
    threads:
      # tomcat最大线程数，默认为200
      max: 800
      # Tomcat启动初始化的线程数，默认值10
      min-spare: 100

# 日志配置
logging:
  level:
    com.demo: debug
    org.springframework: warn

# Spring配置
spring:
  # 文件上传
  servlet:
    multipart:
      # 单个文件大小
      max-file-size: 10MB
      # 设置总上传的文件大小
      max-request-size: 20MB
  datasource:
    # jdbc:h2:F:\activitiDemo\data\demodb
    url: jdbc:h2:file:./data/demodb
    driver-class-name: org.h2.Driver
    username: sa
    password:
  h2:
    console:
      enabled: true

  activiti:
    process-definition-location-prefix: classpath*:/bpmn/
    database-schema-update: true
    check-process-definitions: false
  security:
    user:
      name: admin
      password: 123456

debug: true

4.解决默认耦合spring-security产生的问题

由于activiti默认耦合spring-security，为了方便Demo以最小化方式运行，将Security配置为无需登录即可访问。

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                // 关闭csrf防护
                .csrf().disable()
                .headers().frameOptions().disable()
                .and()
                //定制url访问权限
                .authorizeRequests()
                //无需登录即可访问
                .antMatchers("/**").permitAll()
                .and();
    }

    @Bean
    public UserDetailsService userDetailsService() {
        return new UserDetailsService() {
            @Override
            public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
                return new User("admin", passwordEncoder().encode("123456"),
                        Arrays.asList(new SimpleGrantedAuthority("ROLE_ACTIVITI_USER"), new SimpleGrantedAuthority("GROUP_activitiTeam")));
            }
        };
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}
