Springのc-namespaceの問題 - コンストラクタの引数 '_street'が無効な整数を指定しています

Question

リテラル値をコンストラクタに挿入しているときにc-namespaceの使用を試みています。その名前でコンストラクタの引数を参照すると、問題に遭遇しています。その位置（つまり、0,1,2 ...）で参照すると完全に正常に動作します。

私は（私はSTSを使用しています）日食に変数のデバッグチェックを設定している - Windowsの>設定>ジャワ>コンパイラ>は生成されたクラスファイルに変数の属性を追加しますが、私はまだ同じ問題以下

が私のコードで見ます -

インタフェース

package com.nilaysundarkar.spring.demos; 

public interface Person { 
public void speak(); 
} 

実装

package com.nilaysundarkar.spring.demos; 

import org.springframework.beans.factory.BeanNameAware; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Component; 
import javax.inject.Named; 

@Component 
@Named("Russland") 
public class Russian implements Person, BeanNameAware { 

private String language = "Russian"; 
private Address address; 

@Autowired 
public Russian(Address address){ 
    this.address = address; 
} 

public void speak() { 
    System.out.println("I am a Person. I speak " + language + "."); 
    System.out.println("I stay at " + address + "."); 
} 

public void setBeanName(String beanName) { 
    System.out.println(beanName + " has been initialized."); 
} 

} 

を実行すると

Answer 1

正しい方法は、コンストラクタのパラメータ名と一致する必要がありますc:接頭辞の後の値として、c:streetなくc:_streetを使用することです。
