[TOC] ## 1、搭建maven聚合工程 > 为了以后扩展方便，再此我们搭建一个聚合工程。 ### 1.1 框架搭建   删除src目录  创建一个module工程   目录结构如下：  ### 1.2 pom文件 ~~~ <?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.sxdx</groupId> <artifactId>workflow-activiti</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules> <module>workflow-activiti-rest</module> </modules> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <druid.version>1.1.14</druid.version> <swagger.version>2.9.2</swagger.version> <fastjson.version>1.2.68</fastjson.version> <activiti.version>6.0.0</activiti.version> </properties> <!-- 依赖声明 --> <dependencyManagement> <dependencies> <!-- SpringBoot的依赖配置--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>2.1.1.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> <!--阿里数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>${druid.version}</version> </dependency> <!-- swagger2--> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>${swagger.version}</version> </dependency> <!-- swagger2-UI--> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>${swagger.version}</version> </dependency> <!-- 阿里JSON解析器 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>${fastjson.version}</version> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.1</version> <configuration> <source>${java.version}</source> <target>${java.version}</target> <encoding>${project.build.sourceEncoding}</encoding> </configuration> </plugin> </plugins> </build> </project> ~~~ * workflow-activiti-rest 子工程 ``` <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>workflow-activiti</artifactId> <groupId>org.sxdx</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>workflow-activiti-rest</artifactId> <dependencies> <!-- SpringBoot Web容器 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.2</version> </dependency> <!-- Mysql驱动包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!--阿里数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> <!-- spring-boot-devtools --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> <!-- 表示依赖不会传递 --> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>2.1.1.RELEASE</version> <configuration> <fork>true</fork> <!-- 如果没有该配置，devtools不会生效 --> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> </plugins> <finalName>${project.artifactId}</finalName> </build> </project> ``` ## 2、 改成springboot工程 ### 2.1 设置启动类 ~~~ package com.sxdx.workflow.activiti.rest; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class WorkFlowActivitiRestApplication { public static void main(String[] args) { SpringApplication.run(WorkFlowActivitiRestApplication.class, args); System.out.println("启动成功"); } } ~~~ ### 2.2 application.yml ~~~ # 开发环境配置 server: # 服务器的HTTP端口，默认为80 port: 8080 servlet: # 应用的访问路径 context-path: / tomcat: # tomcat的URI编码 uri-encoding: UTF-8 # tomcat最大线程数，默认为200 max-threads: 800 # Tomcat启动初始化的线程数，默认值25 min-spare-threads: 30 # Spring配置 spring: datasource: driverClassName: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true username: root password: gaoyipeng #druid配置 druid: # 初始连接数 initialSize: 5 # 最小连接池数量 minIdle: 10 # 最大连接池数量 maxActive: 20 # 配置获取连接等待超时的时间 maxWait: 60000 # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 timeBetweenEvictionRunsMillis: 60000 # 配置一个连接在池中最小生存的时间，单位是毫秒 minEvictableIdleTimeMillis: 300000 # 配置一个连接在池中最大生存的时间，单位是毫秒 maxEvictableIdleTimeMillis: 900000 # 配置检测连接是否有效 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false webStatFilter: enabled: true statViewServlet: enabled: true # 设置白名单，不填则允许所有访问 allow: url-pattern: /druid/* # 控制台管理用户名和密码 login-username: login-password: filter: stat: enabled: true # 慢SQL记录 log-slow-sql: true slow-sql-millis: 1000 merge-sql: true wall: config: multi-statement-allow: true ~~~ 通过我们上面的配置我们知道需要新建一个名为activiti的mysql数据库。 最终效果如下：  ## 3、启动 访问：[http://localhost:8080/druid](http://localhost:8080/druid)  ## 4、集成activiti6 在workflow-activiti-rest 的pom 文件中添加 ~~~ <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter-rest-api</artifactId> <version>${activiti.version}</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-json-converter</artifactId> <version>6.0.0</version> <exclusions> <exclusion> <groupId>org.activiti</groupId> <artifactId>activiti-bpmn-model</artifactId> </exclusion> </exclusions> </dependency> <!-- xml解析依赖--> <dependency> <groupId>org.apache.xmlgraphics</groupId> <artifactId>batik-codec</artifactId> <version>1.7</version> </dependency> <dependency> <groupId>org.apache.xmlgraphics</groupId> <artifactId>batik-css</artifactId> <version> 1.7</version> </dependency> <dependency> <groupId>org.apache.xmlgraphics</groupId> <artifactId>batik-svg-dom</artifactId> <version>1.7</version> </dependency> <dependency> <groupId>org.apache.xmlgraphics</groupId> <artifactId>batik-svggen</artifactId> <version>1.7</version> </dependency> ~~~ ### 4.1 排除 Activiti 和 Spring Security 登录验证 再次启动会报错： ~~~ org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [com.sxdx.workflow.activiti.rest.WorkFlowActivitiRestApplication]; nested exception is java.io.FileNotFoundException: class path resource [org/springframework/security/config/annotation/authentication/configurers/GlobalAuthenticationConfigurerAdapter.class] cannot be opened because it does not exist ...... Caused by: java.io.FileNotFoundException: class path resource [org/springframework/security/config/annotation/authentication/configurers/GlobalAuthenticationConfigurerAdapter.class] cannot be opened because it does not exist at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:180) ~[spring-core-5.1.3.RELEASE.jar:5.1.3.RELEASE] at org.springframework.core.type.classreading.SimpleMetadataReader.<init>(SimpleMetadataReader.java:51) ~[spring-core-5.1.3.RELEASE.jar:5.1.3.RELEASE] ~~~ 解决方法： ~~~ @SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, org.activiti.spring.boot.SecurityAutoConfiguration.class, org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class }) public class WorkFlowActivitiRestApplication { public static void main(String[] args) { SpringApplication.run(WorkFlowActivitiRestApplication.class, args); System.out.println("启动成功"); } } ~~~ ### 4.2 application.yml 添加配置 ``` # Spring配置 spring: # activiti 模块 # 解决启动报错：class path resource [processes/] cannot be resolved to URL because it does not exist activiti: check-process-definitions: false ```  ## 5、验证 再次启动程序，能够正常启动。  这是我们看看数据库：  可以看到自动生成了activiti的28张表。至此，基本环境已经搭建完成。
