目錄一、創(chuàng)建springboot工程二、修改maven配置2.1、修改springboot版本號2.2、引入camunda包三、修改application.yaml配置四、創(chuàng)建mysql數(shù)據(jù)庫五、啟動springboot工程六、登錄訪問camunda一、創(chuàng)建springboot工程

使用IDEA工具，選擇File->New->Project，選擇Spring Initialzr

輸入springboot工程基本信息，本示例命名為“camunda-demo1”, jdk版本選擇8

在選擇springboot組件的時候，需要選擇Spring Web、JDBC API、MySql Driver 這三個組件。點(diǎn)擊下一步完成即可。

二、修改maven配置2.1、修改springboot版本號

由于camunda版本與springboot版本有匹配關(guān)系，所以需要修改springboot版本為2.4.3，

官方推薦Camunda7.1.5版本使用Spring Boot 2.4.x版本

具體配置參考camunda官方說明文檔：https://docs.camunda.org/manual/7.15/user-guide/spring-boot-integration/version-compatibility/

Pom.xm代碼片段:

<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.4.3</version><relativePath/> </parent>2.2、引入camunda包

由于本示例要使用camunda流程引擎、web界面、Rest服務(wù)接口，所以需要導(dǎo)入camunda-bpm-spring-boot-starter、camunda-bpm-spring-boot-starter-rest、camunda-bpm-spring-boot-starter-webapp這三個依賴包，如果僅僅是使用流程引擎，只需要引入camunda-bpm-spring-boot-starter就可以了。

完整的pom.xml文件如下：

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd'> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.4.3</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>camunda-demo1</artifactId> <version>0.0.1-SNAPSHOT</version> <name>camunda-demo1</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.camunda.bpm.springboot</groupId> <artifactId>camunda-bpm-spring-boot-starter</artifactId> <version>7.15.0</version> </dependency> <dependency> <groupId>org.camunda.bpm.springboot</groupId> <artifactId>camunda-bpm-spring-boot-starter-rest</artifactId> <version>7.15.0</version> </dependency> <dependency> <groupId>org.camunda.bpm.springboot</groupId> <artifactId>camunda-bpm-spring-boot-starter-webapp</artifactId> <version>7.15.0</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>三、修改application.yaml配置

打開工程目錄下的mainresourcesapplication.yaml文件，如果沒有該文件，手動新建一個，錄入如下信息。

# Find more available configuration properties on the following pages of the documentation. # https://docs.camunda.org/manual/latest/user-guide/camunda-bpm-run/#configure-camunda-bpm-run # https://docs.camunda.org/manual/latest/user-guide/spring-boot-integration/configuration/#camunda-engine-properties camunda.bpm: generic-properties.properties: javaSerializationFormatEnabled: true admin-user: id: demo password: demo run: # https://docs.camunda.org/manual/latest/user-guide/camunda-bpm-run/#cross-origin-resource-sharing cors: enabled: true allowed-origins: '*' # datasource configuration is required spring.datasource: url: jdbc:mysql://127.0.0.1:3306/camunda715?characterEncoding=UTF-8&useUnicode=true&useSSL=false&zeroDateTimeBehavior=convertToNull&serverTimezone=Asia/Shanghai driver-class-name: com.mysql.cj.jdbc.Driver username: root password: root # By default, Spring Boot serves static content from any directories called /static or /public or /resources or # /META-INF/resources in the classpath. To prevent users from accidentally sharing files, this is disabled here by setting static locations to NULL. # https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-spring-mvc-static-content spring.web.resources: static-locations: NULL

本示例使用的是mysql數(shù)據(jù)庫，數(shù)據(jù)庫URL、username、 password 跟后面數(shù)據(jù)庫信息保存一致。

四、創(chuàng)建mysql數(shù)據(jù)庫

Camunda默認(rèn)使用已預(yù)先配置好的H2數(shù)據(jù)庫，本示例使用mysql數(shù)據(jù)庫，需要提前創(chuàng)建mysql數(shù)據(jù)庫并導(dǎo)入Camunda建表腳本。

為Camunda平臺創(chuàng)建一個數(shù)據(jù)庫模式，名稱為camunda715

導(dǎo)入SQL腳本。執(zhí)行創(chuàng)建所有必需的表和默認(rèn)索引的SQL DDL腳本。這些腳本可以在configuration/sql/create文件夾中找到。共2個腳本，都需要導(dǎo)入。

導(dǎo)入完成后的表結(jié)構(gòu)，共40張表：

詳細(xì)配置方法參考：https://lowcode.blog.csdn.net/article/details/117564836

五、啟動springboot工程

創(chuàng)建springboot工程的時候，自動生成了SpringBootApplication啟動類，運(yùn)行改類啟動即可。

package com.example.demo1;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class CamundaDemo1Application {public static void main(String[] args) {SpringApplication.run(CamundaDemo1Application.class, args);}}

六、登錄訪問camunda

訪問：http://localhost:8080,

默認(rèn)賬號密碼demo/demo

登錄成功后進(jìn)入camunda控制臺

至此，完成了springboot2.4.3+camunda7.15+mysql的集成，后續(xù)的如何設(shè)計(jì)流程、如何啟動流程、如何審批流程等操作，跟非springboot方式是一致的，請參考前面的文章。
