为什么在构建端点时，java bean不会转换为camel IdempotentRepository？

Question

我试过这个解决办法，但我的实现似乎并不工作：How to access Default Idempotent Repository map from java dsl?

@Bean 
@Scope("prototype") 
public static IdempotentRepository<String> getMemoryCache() { 
    return new MemoryIdempotentRepository(); 
} 

，然后我尝试做一个参考，以它在我的URI，它抛出一个异常，这样说：

java.lang.IllegalArgumentException: Could not find a suitable setter for property: idempotentRepository as there isn't a setter method with same type: java.lang.String nor type conversion possible: No type converter available to convert from type: java.lang.String to the required type: org.apache.camel.spi.IdempotentRepository with value #getMemoryCache() 

..我做了什么来构建URI：

URIBuilder builder = _INSTANCE.getSourceFolderEndpointUriBuilder(exchange); 
builder.setScheme("file"); 
builder.addParameter("recursive", "true"); 
builder.addParameter("readLock", "none"); 
builder.addParameter("idempotentRepository", "#getMemoryCache()"); 

Answer 1

我解决它， 豆必须是在配置类，然后引用该bean，它不应该有括号。

builder.addParameter("idempotentRepository", "#getMemoryCache");
