在线编辑器可以直接参考，springMVC集成activiti-explorer5.22(一)中的第2、3、4步,以及springMVC集成activiti-explorer5.22(二)的配置，基本整合基本完成，这里来着重说一下在springboot中需要修改的地方.

1.修改ModelSaveRestResource.java类

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;

import org.activiti.editor.constants.ModelDataJsonConstants;
import org.activiti.engine.ActivitiException;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.repository.Model;
import org.apache.batik.transcoder.TranscoderInput;
import org.apache.batik.transcoder.TranscoderOutput;
import org.apache.batik.transcoder.image.PNGTranscoder;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.util.MultiValueMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;

import com.alibaba.fastjson.JSONObject;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;

@RestController
@RequestMapping(value = "/service")
public class ModelSaveRestResource implements ModelDataJsonConstants {

	private static final Logger LOGGER = LogManager.getLogger(ModelSaveRestResource.class);

	@Autowired
	private RepositoryService repositoryService;

	@Autowired
	private ObjectMapper objectMapper;

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

2.修改stencilset.json文件的获取位置

由于在Springboot中静态文件都是放在resources/static中的，因此也需要修改StencilsetRestResource.java中获取文件的位置,如下即可

InputStream stencilsetStream = getClass().getClassLoader().getResourceAsStream("static/activiti/stencilset.json");

3.解决流程图中文保存乱码的问题

新建一个CustomActivitiConfig.java的配置类即可,代码如下

import org.activiti.spring.SpringProcessEngineConfiguration;
import org.activiti.spring.boot.ProcessEngineConfigurationConfigurer;
import org.springframework.stereotype.Component;

@Component
public class CustomActivitiConfig implements ProcessEngineConfigurationConfigurer {

	/**
	 * Overriding
	 * <h5>功能:设置流程图中中文字体,防止流程图显示乱码</h5>	
	 * @param processEngineConfiguration
	 */
	@Override
	public void configure(SpringProcessEngineConfiguration processEngineConfiguration) {
		processEngineConfiguration.setActivityFontName("宋体");
		processEngineConfiguration.setLabelFontName("宋体");
		processEngineConfiguration.setAnnotationFontName("宋体");
	}
}

至此,整合结束
