把flowable弄到自己項目中，遇到的各種坑總結。

一、下載官方提供war包

　　1、在工程下建flowable包，將內容復制到下面

　　復制flowable-modeler\WEB-INF\classes\static到自己項目中

　　

　　2修改js引用路徑 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、添加用戶認證，目前比較靠譜的代碼如下:

　　

@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、啟動項目，看看抱什么錯誤，然后挨個修復

　　　　　　

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.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor.postProcessBeforeInitialization(InitDestroyAnnotationBeanPostProcessor.java:135)
    ... 31 common frames omitted

　　　　添加idm配置，不通版本可能對應key不一樣，這個根據提示自己添加就行

　　　　

idm.app.url=http://localhost:8080/
idm.admin.user=admin
idm.admin.password=test

　　2、重啟項目可以看到成功頁面，其實還未成功，和后台數據還沒連起來

　　創建流程報錯

　　

 

 

 　　服務起返回: {"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"}

　　

　　發現mybatis模板沒有綁定:

　　添加配置，多個可以用,隔開

mybatis-plus.mapper-locations=classpath*:META-INF/modeler-mybatis-mappings/*.xml

　　　　

　　3、再次重啟后繼續報錯

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，發下如下代碼

　

        <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=

　　如果遇到缺少個別參數，可以在js中通過搜索地址，然后再請求中添加內容　　　　

重啟終於好了！！！！！！！！！！

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

　　其實還未好，修改模板會出現不支持請求格式，可以重寫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;
    }
