把flowable弄到自己项目中，遇到的各种坑总结。
一、下载官方提供war包
1、在工程下建flowable包，将内容复制到下面
复制flowable-modeler\WEB-INF\classes\static到自己项目中
2修改js引用路径 app-cfg.js
FLOWABLE.CONFIG = { 'onPremise' : true, 'contextRoot' : "", 'webContextRoot' : "/static/flowable", 'datesLocalization' : false };
3、引入springboot官方jar包
<dependency>
<groupId>org.flowable</groupId>
<artifactId>flowable-spring-boot-starter</artifactId>
<version>${flowable.version}</version>
</dependency>
<dependency>
<groupId>org.flowable</groupId>
<artifactId>flowable-ui-modeler-rest</artifactId>
<version>${flowable.version}</version>
<exclusions>
<exclusion>
<artifactId>guava</artifactId>
<groupId>com.google.guava</groupId>
</exclusion>
</exclusions>
</dependency>
4、添加用户认证，目前比较靠谱的代码如下:
@Controller
@RequestMapping("/app")
public class AccountUtil{
@RequestMapping("/rest/account")
@ResponseBody
public UserRepresentation getAccount() {
User user=new User() {
@Override
public String getId() {
return "admin";
}
@Override
public void setId(String s) {
}
@Override
public String getFirstName() {
return "admin";
}
@Override
public void setFirstName(String s) {
}
@Override
public void setLastName(String s) {
}
@Override
public String getLastName() {
return "admin";
}
@Override
public void setEmail(String s) {
}
@Override
public String getEmail() {
return "admin";
}
@Override
public String getPassword() {
return "admin";
}
@Override
public void setPassword(String s) {
}
@Override
public boolean isPictureSet() {
return false;
}
};
user.setId("admin");
SecurityUtils.assumeUser(user);
UserRepresentation userRepresentation = new UserRepresentation();
userRepresentation.setId("admin");
userRepresentation.setFirstName("admin");
List<String> privileges=new ArrayList<>();
List<String> pris = new ArrayList<>();
pris.add(DefaultPrivileges.ACCESS_MODELER);
pris.add(DefaultPrivileges.ACCESS_IDM);
pris.add(DefaultPrivileges.ACCESS_ADMIN);
pris.add(DefaultPrivileges.ACCESS_TASK);
userRepresentation.setPrivileges(privileges);
return userRepresentation;
}
}
二、填坑
1、启动项目，看看抱什么错误，然后挨个修复
Caused by: java.lang.IllegalStateException: Required key 'idm.app.url' not found at org.springframework.core.env.AbstractPropertyResolver.getRequiredProperty(AbstractPropertyResolver.java:184) at org.springframework.core.env.AbstractEnvironment.getRequiredProperty(AbstractEnvironment.java:552) at org.flowable.app.service.idm.RemoteIdmServiceImpl.init(RemoteIdmServiceImpl.java:67) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor$LifecycleElement.invoke(InitDestroyAnnotationBeanPostProcessor.java:365) at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor$LifecycleMetadata.invokeInitMethods(InitDestroyAnnotationBeanPostProcessor.java:308) at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor.postProcessBeforeInitialization(InitDestroyAnnotationBeanPostProcessor.java:135) ... 31 common frames omitted
添加idm配置，不通版本可能对应key不一样，这个根据提示自己添加就行
idm.app.url=http://localhost:8080/ idm.admin.user=admin idm.admin.password=test
2、重启项目可以看到成功页面，其实还未成功，和后台数据还没连起来
创建流程报错
服务起返回: {"message":"Internal server error","exception":"nested exception is org.apache.ibatis.exceptions.PersistenceException: \r\n### Error querying database. Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for org.flowable.app.domain.editor.Model.selectModelByParameters\r\n### Cause: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for org.flowable.app.domain.editor.Model.selectModelByParameters"}
发现mybatis模板没有绑定:
添加配置，多个可以用,隔开
mybatis-plus.mapper-locations=classpath*:META-INF/modeler-mybatis-mappings/*.xml
3、再次重启后继续报错
Caused by: org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. The XML location is 'URL [jar:file:/D:/Dev/Repository/org/flowable/flowable-ui-modeler-logic/6.1.2/flowable-ui-modeler-logic-6.1.2.jar!/META-INF/modeler-mybatis-mappings/Model.xml]'.

找到Model.xml，发下如下代码
<result property="tenantId" column="tenant_id" jdbcType="VARCHAR" />
添加如下配置
mybatis-plus.configuration-properties.blobType=BLOB mybatis-plus.configuration-properties.boolValue=TRUE mybatis-plus.configuration-properties.prefix=
如果遇到缺少个别参数，可以在js中通过搜索地址，然后再请求中添加内容
重启终于好了！！！！！！！！！！
其实还未好，修改模板会出现不支持请求格式，可以重写WebMvcConfigurationSupport.requestMappingHandlerAdapter方法
@Override public RequestMappingHandlerAdapter requestMappingHandlerAdapter() { RequestMappingHandlerAdapter adapter = new RequestMappingHandlerAdapter(); List<HttpMessageConverter<?>> converters = adapter.getMessageConverters(); MappingJackson2HttpMessageConverter jsonConverter = new MappingJackson2HttpMessageConverter(); List<MediaType> supportedMediaTypes = new ArrayList<>(); MediaType textMedia = new MediaType(MediaType.TEXT_PLAIN, Charset.forName("UTF-8")); supportedMediaTypes.add(textMedia); MediaType jsonMedia = new MediaType(MediaType.APPLICATION_JSON, Charset.forName("UTF-8")); supportedMediaTypes.add(jsonMedia); MediaType urlencodeMedia = new MediaType(MediaType.APPLICATION_FORM_URLENCODED, Charset.forName("UTF-8")); supportedMediaTypes.add(urlencodeMedia); jsonConverter.setSupportedMediaTypes(supportedMediaTypes); converters.add(jsonConverter); adapter.setMessageConverters(converters); return adapter; }
