集成Activiti之前,必须搞清楚其中的依赖关系,才能在Gradle里进行配置.
依赖关系:
例如,其中activiti-engine依赖于activiti-bpmn-converter,而activiti-bpmn-converter又依赖于activiti-bpmn-model
那么这以下的引用都是要设置的,缺一不可,否则portlet会无法注入进OSGi容器
org.activiti:activiti-engine:jar:5.xx.0
+- org.activiti:activiti-bpmn-converter:jar:5.xx.0:compile
| \- org.activiti:activiti-bpmn-model:jar:5.xx.0:compile
| +- com.fasterxml.jackson.core:jackson-core:jar:2.2.3:compile
| \- com.fasterxml.jackson.core:jackson-databind:jar:2.2.3:compile
| \- com.fasterxml.jackson.core:jackson-annotations:jar:2.2.3:compile
+- org.activiti:activiti-process-validation:jar:5.xx.0:compile
+- org.activiti:activiti-image-generator:jar:5.xx.0:compile
+- org.apache.commons:commons-email:jar:1.2:compile
| +- javax.mail:mail:jar:1.4.1:compile
| \- javax.activation:activation:jar:1.1:compile
+- org.apache.commons:commons-lang3:jar:3.3.2:compile
+- org.mybatis:mybatis:jar:3.2.5:compile
+- org.springframework:spring-beans:jar:4.0.6.RELEASE:compile
| \- org.springframework:spring-core:jar:4.0.6.RELEASE:compile
+- joda-time:joda-time:jar:2.6:compile
+- org.slf4j:slf4j-api:jar:1.7.6:compile
+- org.slf4j:jcl-over-slf4j:jar:1.7.6:compile
接下来,需要完成Gradle的设置,
全部:

需要注意的是，还需要把jar文件放置在osgi的modules目录下，非常重要
这样一个Portlet就开发出来了，感觉靠拖拽放在页面，再设置访问权限有些繁琐，我们还想把它直接放进控制面板里。
