buildBeanDefinition與Spring Statemachine Framework失敗

Question

我想在我的項目中使用Spring Statemachine框架，但是我在編譯時遇到了一個建築bean定義錯誤。

我在我的Spring MVC應用程序中跟隨step 7。我沒有使用SpringBoot，但我不認爲我錯過了任何子文件。

這裏是我的StateMachineConfig文件代碼：

import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.statemachine.config.EnableStateMachine; 
import org.springframework.statemachine.config.EnumStateMachineConfigurerAdapter; 
import org.springframework.statemachine.config.builders.StateMachineConfigurationConfigurer; 
import org.springframework.statemachine.config.builders.StateMachineStateConfigurer; 
import org.springframework.statemachine.config.builders.StateMachineTransitionConfigurer; 
import org.springframework.statemachine.listener.StateMachineListener; 
import org.springframework.statemachine.listener.StateMachineListenerAdapter; 
import org.springframework.statemachine.state.State; 

import java.util.EnumSet; 


@Configuration 
@EnableStateMachine 
public class StateMachineConfig 
     extends EnumStateMachineConfigurerAdapter<States, Events> { 

    @Override 
    public void configure(StateMachineConfigurationConfigurer<States, Events> config) 
      throws Exception { 
     config 
       .withConfiguration() 
       .autoStartup(true) 
       .listener(listener()); 
    } 

    @Override 
    public void configure(StateMachineStateConfigurer<States, Events> states) 
      throws Exception { 
     states 
       .withStates() 
       .initial(States.SI) 
       .states(EnumSet.allOf(States.class)); 
    } 

    @Override 
    public void configure(StateMachineTransitionConfigurer<States, Events> transitions) 
      throws Exception { 
     transitions 
       .withExternal() 
       .source(States.SI).target(States.S1).event(Events.E1) 
       .and() 
       .withExternal() 
       .source(States.S1).target(States.S2).event(Events.E2); 
    } 

    @Bean 
    public StateMachineListener<States, Events> listener() { 
     return new StateMachineListenerAdapter<States, Events>() { 
      @Override 
      public void stateChanged(State<States, Events> from, State<States, Events> to) { 
       System.out.println("State change to " + to.getId()); 
      } 
     }; 
    } 
} 

這是我嘗試使用的StateMachine中（注控制器：我刪除了的statemachine作爲的IntelliJ的實例化上面的標籤@Autowired不停地說「的‘的StateMachine’類型沒有發現豆」這可能是我的問題的罪魁禍首）：？

@Controller 
@RequestMapping("/") 
public class HomeController { 

    private StateMachine<States, Events> stateMachine; 

    @RequestMapping(method = RequestMethod.GET) 
    public String index() { 
      stateMachine.sendEvent(Events.E1); 
      return "redirect:/target/list"; 
    } 
} 

Answer 1

NoSuchMethodError如果點到春天核心類意味着有框架的版本的查詢股價。您可能會讓statemachine pom解析某些版本，而您自己的版本會添加其他內容。

你的maven或gradle構建文件可能會顯示爲什麼核心框架jar有不同的版本。如果使用啓動，那麼你會得到正確的版本，沒有它你需要手動管理版本。
