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

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
<!-- 此plugin可以用利用此plugin，把源代码中的xml文件，打包到相应位置，这里主要是为了打包Mybatis的mapper.xml文件，如下只 是截取了与 maven-resources-plugin 相关pom文件配置，其它部分按照自己的工程目录来。 --> <plugin> <artifactId>maven-resources-plugin</artifactId> <executions> <execution> <id>copy-xmls</id> <phase>process-sources</phase> <goals> <goal>copy-resources</goal> </goals> <configuration> <outputDirectory>target/classes</outputDirectory> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> <excludes> <exclude>static/fonts/**</exclude> <exclude>static/plugins/processes/editor-app/**</exclude> </excludes> </resource> <resource> <directory>src/main/resources</directory> <filtering>false</filtering> <includes> <include>static/fonts/**</include> <include>static/plugins/processes/editor-app/**</include> </includes> </resource> </resources> </configuration> </execution> </executions> </plugin>
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);
}
}
