Question

在我的项目中，我混合了Spring Javaconfig和XML配置，由于Spring具有方便的批处理命名空间，我只使用它。在xml配置中，我指的是@JobScope监听器，如此

<step abstract="true" id="hist">
    <listeners>
        <listener ref="histListener"/>
    </listeners>
</step>

此侦听器定义为Javaconfig @Bean

@Bean
@JobScope
public HistListener histListener(@Value("#{jobParameters[inputFilePath]}") String inputFilePath) {
  return new HistListener(inputFilePath);
}

问题是，当解析XML时，它期望在没有参数的情况下调用代理bean histListener 构造函数，即使它需要作业注入的 inputFilePath 参数范围@Value注释。

我已经能够毫无问题地将@Bean转换为其XML等价物，但似乎在这种情况下，XML和JavaConfig不相处。有没有人找到解决方案？

在xml配置中引用作业范围java bean
