spring-boot集成activiti的model遇到问题汇总

按照网上的七拼八凑整合网页版的部署将遇到的问题归置如下：

本人的springboot版本是:1.5.13.RELEASE

工作流相关：

 
        
            org.activiti
            activiti-spring-boot-starter-basic
            ${activiti.version}
        
        
        
        
            org.activiti
            activiti-diagram-rest
            ${activiti.version}
        
        
        
            org.activiti
            activiti-modeler
            ${activiti.version}
        

1、启动之后访问跳出输入用户名，密码，原因：activiti集成的安全校验

解决：在启动类加入：

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

2、在线编辑器modeler.html访问的时候是空白，大部分是因为这个页面所需要的元素没有取到，检查相关的路径，

editor-app/app-cfg.js这个文件修改如下（都是按照实际项目配置来的，这个service可以按照自己实际的来，后面的三个类保持一致即可）
ACTIVITI.CONFIG = {
	//'contextRoot' : '/activiti-explorer/service',
	'contextRoot' : '/service'
};
查看是否改成系统一致的路径，
迁移过来的三个类：StencilsetRestResource.java、ModelEditorJsonRestResource.java、ModelSaveRestResource.java统一在类上加@RequestMapping(value = "/service")

修改StencilsetRestResource.java(如果在拷贝stencilset.json时没有放在resources目录下)
InputStream stencilsetStream = this.getClass().getClassLoader().getResourceAsStream("stencilset.json");把它改为相应的位置，

　3、modeler.html？modelId=xxx里面的符号出现了方框（svg矢量图形都变成了不可辨识的字符），原因就是都配置了pom的资源路径下，pom会扫面资源路径，把变量替换成相应的值，二进制的文件就会收到破坏，把先关文件不扫描即可，如下配置

				
				    maven-resources-plugin
				    
				        
				            copy-xmls
				            process-sources
				            
				                copy-resources
				            
				            
				                target/classes
				                
						            
						                src/main/resources
						                true
						                
						                    static/fonts/**
						                    static/plugins/processes/editor-app/**
						                
						            
						            
						                src/main/resources
						                false
						                
						                    static/fonts/**
						                    static/plugins/processes/editor-app/**
						                
						            
						        
				            
				        
				    
				

4、model.html保存页面报错（400错误Required request body is missing），修改ModelSaveRestResource方法的参数，可以整个替换掉这个方法即可

@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);
		}
	}
