spring-boot集成activiti的model遇到問題匯總

按照網上的七拼八湊整合網頁版的部署將遇到的問題歸置如下：

本人的springboot版本是:1.5.13.RELEASE

1、啟動之后訪問跳出輸入用戶名，密碼，原因：activiti集成的安全校驗

解決：在啟動類加入：

@EnableAutoConfiguration(exclude = { org.activiti.spring.boot.SecurityAutoConfiguration.class,
		org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class })

2、在線編輯器modeler.html訪問的時候是空白，大部分是因為這個頁面所需要的元素沒有取到，檢查相關的路徑，

editor-app/app-cfg.js這個文件修改如下（都是按照實際項目配置來的，這個service可以按照自己實際的來，后面的三個類保持一致即可）
ACTIVITI.CONFIG = {
	//'contextRoot' : '/activiti-explorer/service',
	'contextRoot' : '/service'
};
查看是否改成系統一致的路徑，
遷移過來的三個類：StencilsetRestResource.java、ModelEditorJsonRestResource.java、ModelSaveRestResource.java統一在類上加@RequestMapping(value = "/service")

修改StencilsetRestResource.java(如果在拷貝stencilset.json時沒有放在resources目錄下)
InputStream stencilsetStream = this.getClass().getClassLoader().getResourceAsStream("stencilset.json");把它改為相應的位置，

　3、modeler.html？modelId=xxx里面的符號出現了方框（svg矢量圖形都變成了不可辨識的字符），原因就是都配置了pom的資源路徑下，pom會掃面資源路徑，把變量替換成相應的值，二進制的文件就會收到破壞，把先關文件不掃描即可，如下配置

<!--
					此plugin可以用利用此plugin，把源代碼中的xml文件，打包到相應位置，這里主要是為了打包Mybatis的mapper.xml文件，如下只
					是截取了與 maven-resources-plugin 相關pom文件配置，其它部分按照自己的工程目錄來。

				<plugin>
				    <artifactId>maven-resources-plugin</artifactId>
				    <executions>
				        <execution>
				            <id>copy-xmls</id>

				            </configuration>
				        </execution>
				    </executions>
				</plugin>

4、model.html保存頁面報錯（400錯誤Required request body is missing），修改ModelSaveRestResource方法的參數，可以整個替換掉這個方法即可

@RequestMapping(value = "/model/{modelId}/save", method = RequestMethod.PUT)
	@ResponseStatus(value = HttpStatus.OK)
	public void saveModel(@PathVariable String modelId, String name, String description, String json_xml,
			String svg_xml) {
		try {
			Model model = repositoryService.getModel(modelId);

			ObjectNode modelJson = (ObjectNode) objectMapper.readTree(model.getMetaInfo());

			modelJson.put(MODEL_NAME, name);
			modelJson.put(MODEL_DESCRIPTION, description);
			model.setMetaInfo(modelJson.toString());
			model.setName(name);

			repositoryService.saveModel(model);

			repositoryService.addModelEditorSource(model.getId(), json_xml.getBytes("utf-8"));

			InputStream svgStream = new ByteArrayInputStream(svg_xml.getBytes("utf-8"));
			TranscoderInput input = new TranscoderInput(svgStream);

			PNGTranscoder transcoder = new PNGTranscoder();
			// Setup output
			ByteArrayOutputStream outStream = new ByteArrayOutputStream();
			TranscoderOutput output = new TranscoderOutput(outStream);

			// Do the transformation
			transcoder.transcode(input, output);
			final byte[] result = outStream.toByteArray();
			repositoryService.addModelEditorSourceExtra(model.getId(), result);
			outStream.close();

		} catch (Exception e) {
			LOGGER.error("Error saving model", e);
			throw new ActivitiException("Error saving model", e);
		}
	}
