Spring：如何在Spring配置中注入ENUM？ [英] Spring: How do I inject ENUM in Spring configuration?

问题描述

我有一个 ENUM 作为

package com.myorg.sparrow.s3Environment;

import javax.annotation.Nonnull;

public enum DocumentType {
    Document("document/", ".xml.gz", "binary/octet-stream", "gzip", true);

    private final String path;
    private final String suffix;
    private final String contentType;
    private final String contentEncoding;
    private final Boolean compress;

    private DocumentType(@Nonnull final String path, @Nonnull final String suffix,
                         @Nonnull final String contentType, @Nonnull final String contentEncoding,
                         @Nonnull final Boolean compress) {
        this.path = path;
        this.suffix = suffix;
        this.contentType = contentType;
        this.contentEncoding = contentEncoding;
        this.compress = compress;
    }

    @Nonnull
    public String getPath() {
        return path;
    }

    @Nonnull
    public String getSuffix() {
        return suffix;
    }

    @Nonnull
    public String getContentType() {
        return contentType;
    }

    @Nonnull
    public String getContentEncoding() {
        return contentEncoding;
    }

    @Nonnull
    public Boolean isCompress() {
        return compress;
    }
}

我想注入这个 DocumentType.Document in Spring 配置文件

I want to inject this value of DocumentType.Document in Spring configuration file

   <bean id="s3Service" class="com.myorg.sparrow.business.xml.persist.S3Service">
        <constructor-arg ref="awsCredentials" />
        <constructor-arg value="**DocumentType.DOCUMENT**" /> // how do I inject it here?
        <constructor-arg value="${com.myorg.sparrow.s3EnvironmentConfiguration.S3EnvironmentConfigurator-destBucketName}" />
    </bean>

如何在

<constructor-arg value="**DocumentType.DOCUMENT**" /> // how do I inject it here?

我对Spring框架非常新，不知道如何实现这个

I am very new to Spring framework and not sure how to achieve this

谢谢

推荐答案

 <bean id="s3Service" class="com.myorg.sparrow.business.xml.persist.S3Service">
        <constructor-arg ref="awsCredentials" />
        <constructor-arg value="Document" /> // We love Spring because it is simpler than we expect
        <constructor-arg value="${com.myorg.sparrow.s3EnvironmentConfiguration.S3EnvironmentConfigurator-destBucketName}" />
    </bean>
