jasypt 属性占位符不起作用

Question

我有这个属性文件：

secret.key = ENC(foobar)
region = ABC

然后在 config.xml:

<spring:beans>

    <encryption:encryptor-config id="eConf" password-sys-property-name="MULE_ENCRYPTION_PASSWORD" algorithm="PBEWithMD5AndDES" password="" />
    <encryption:string-encryptor id="stringEnc" config-bean="eConf" />
    <encryption:encryptable-property-placeholder encryptor="stringEnc" location="${env}.properties" />

</spring:beans>

但是属性占位符不起作用，例如：

<sqs:config secretKey="${secret.key}" region="${region}"></sqs-config>

有人知道为什么吗？

Answer 1

加密密码需要在ENC()函数中写入，并且应该加密。

让我们考虑在密码值为 Login@123 的属性文件中......现在属性文件中的加密值将是:-

password=ENC(B0u7D8wLwq/ugin31KNpP78gBcLP7VIN)

Step1 :- 我们可以在 \jasypt-1.9.2\bin 目录的命令提示符下使用以下命令生成密钥 :- encrypt input="Login@123" password=sqlpassword algorithm=PBEWithMD5AndDES

Step2 :- 在运行环境中我们需要给（右击->运行 As->运行配置->环境）：-变量：- MULE_ENCRYPTION_PASSWORD 和值：-sqlpassword

在你的Mule配置中，你需要按如下方式配置它:-

 <spring:beans>
        <spring:bean id="environmentVariablesConfiguration" class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
            <spring:property name="algorithm" value="PBEWithMD5AndDES"/>
            <spring:property name="passwordEnvName" value="MULE_ENCRYPTION_PASSWORD"/>
        </spring:bean>

        <!-- The will be the encryptor used for decrypting configuration values. -->
        <spring:bean id="configurationEncryptor" class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
            <spring:property name="config" ref="environmentVariablesConfiguration"/>
        </spring:bean>

        <!-- The EncryptablePropertyPlaceholderConfigurer will read the -->
        <!-- .properties files and make their values accessible as ${var} -->
        <!-- Our "configurationEncryptor" bean (which implements -->
        <!-- org.jasypt.encryption.StringEncryptor) is set as a constructor arg. -->

        <spring:bean id="propertyConfigurer" class="org.jasypt.spring.properties.EncryptablePropertyPlaceholderConfigurer">
            <spring:constructor-arg ref="configurationEncryptor"/>
            <spring:property name="locations">
                <spring:list>
                    <spring:value>conf/yourPropertyFile.properties</spring:value>
                </spring:list>
            </spring:property>
        </spring:bean>

然后你可以使用像这样的加密值：- ${password}

我遇到了类似的问题，我按照 Activemq web site . In my case issue was PropertyPlaceholderConfigurer bean was loaded for to load other properties before the EncryptablePropertyPlaceholderConfigurer bean. So remove PropertyPlaceholderConfigurer bean's if any just add EncryptablePropertyPlaceholderConfigurer bean even for other non-encrypted properties as explained in Activemq 中的说明配置了所有内容，然后一切正常。
