在使用flowable集成 spring boot的时候会经常遇到中文乱码的情况，因此本文重点讲解如何解决flowable的中文乱码问题。

1.flowable 集成spring boot(基础)

2.自定义配置器修改流程引擎配置类ProcessEngineConfigurationConfigurer  。

3.测试ProcessEngineConfigurationConfigurer

4.spring boot flowable集成原理

---

1.flowable 集成spring boot

---

flowable 集成spring boot集成可以参考flowable 集成spring boot。

---

2.自定义配置器修改流程引擎配置类。

---

自定义配置器修改流程引擎配置类代码如下：

import org.flowable.spring.SpringProcessEngineConfiguration;
import org.flowable.spring.boot.ProcessEngineConfigurationConfigurer;
import org.springframework.stereotype.Component;
@Component
public class ShareniuProcessEngineConfigurationConfigurer implements ProcessEngineConfigurationConfigurer  {
public void configure(SpringProcessEngineConfiguration processEngineConfiguration) {
processEngineConfiguration.setActivityFontName("宋体");
processEngineConfiguration.setLabelFontName("宋体");
processEngineConfiguration.setAnnotationFontName("宋体");
System.out.println("ShareniuProcessEngineConfigurationConfigurer#############");
System.out.println(processEngineConfiguration.getActivityFontName());
}
}

注意：

SpringProcessEngineConfiguration类为spring boot默认使用的流程引擎配置类，这一点一定要注意

---

3.测试ProcessEngineConfigurationConfigurer

---

运行如下类Application：

@RestController
@SpringBootApplication()
public class Application {
@RequestMapping("/task")
String task() {
System.out.println("################################" + taskService);
return taskService.toString();
}
@Autowired
private TaskService taskService;
@Autowired
private ProcessEngine processEngine;
@RequestMapping("/")
String index() {
System.out.println("################################taskService" + taskService);
System.out.println("################################processEngine" + processEngine);
return "xxxxxxxxxxxxx";
}
public static void main(String[] args) {
SpringApplication springApplication = new SpringApplication(Application.class);
springApplication.run(args);
}
}

程序的输出如下：

ShareniuProcessEngineConfigurationConfigurer#############

宋体

证明我们已经成功修改了默认的字体。

---

4.原理

---

AbstractProcessEngineAutoConfiguration类的核心代码如下：

public abstract class AbstractProcessEngineAutoConfiguration   extends AbstractProcessEngineConfiguration {
@Autowired(required = false)
private ProcessEngineConfigurationConfigurer processEngineConfigurationConfigurer;
protected SpringProcessEngineConfiguration baseSpringProcessEngineConfiguration(DataSource dataSource, PlatformTransactionManager platformTransactionManager,
SpringAsyncExecutor springAsyncExecutor) throws IOException {
......//省略
if (processEngineConfigurationConfigurer != null) {
processEngineConfigurationConfigurer.configure(conf);
}
return conf;
}
}

道理非常的简单，如果存在processEngineConfigurationConfigurer，则调用该类中的configure方法。
