java - 如何将 Jasypt 与 Spring Autowiring 一起使用？

Question

我已经看到了一些没有自动接线的解决方案，但我正在尝试让它与自动接线一起使用。自上周以来我一直在尝试此操作，但没有找到适合我的情况的解决方案，可能是我没有正确实现它，所以任何帮助都会很棒。

我有一个属性文件myprops.properties:

Wsdl=someurl
UserName=admin
UserPassword=ENC(encriptedpassword)

并在我替换的 servlet.xml 文件中

<context:property-placeholder location="classpath*:myprops.properties" />

与

    <bean id="propertyPlaceholderConfigurer"
            class="org.jasypt.spring.properties.EncryptablePropertyPlaceholderConfigurer">
            <constructor-arg ref="configurationEncryptor" />
            <property name="location" value="classpath:myprops.properties" />
        </bean>
        <bean id="configurationEncryptor" class="org.jasypt.encryption.pbe.StandardPBEStringEncryptor">
            <property name="config" ref="environmentVariablesConfiguration" />
        </bean>
        <bean id="environmentVariablesConfiguration"
              class="org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig">
              <property name="algorithm" value="PBEWithMD5AndDES" />
              <property name="passwordEnvName" value="APP_ENCRYPTION_PASSWORD" />
</bean>

在我的 service.java 中，我自动连接这些值，如下所示:

    @Autowired
    public void setUserPassword(@Value("${UserPassword}") String userPassword) {
        this.userPassword = userPassword;
    }

    @Autowired
    public void setUserName(@Value("${UserName}") String userName) {
        this.userName = userName;
    }

    @Autowired
    public void setWsdl(@Value("${Wsdl}") String wsdl) {
        this.wsdl = wsdl;
    }

事情是当我没有加密密码时，即 UserPassword=nonencriptedpassword

但是当我对其进行加密并使用 ENC() 时，我收到以下错误

    at org.jasypt.encryption.pbe.StandardPBEStringEncryptor.decrypt(StandardPBEStringEncryptor.java:705)
    Truncated. see log file for complete stacktrace

这可能是一些我不知道或忽略的愚蠢简单的事情，但我已经尝试按照 Jasypt wiki 上的教程进行操作。和网站以及教程 xmx1024以及 jayway我确信我已经使用自动连线找到了一个，但我似乎无法再次找到它。

仅供引用:我正在使用 spring 3.0.4、Spring Security 3.0.4 和 jasypt 1.9

任何帮助都会很棒

更新

我已将环境变量APP_ENCRYPTION_PASSWORD设置为等于纯文本密码，并将属性文件中的密码设置为加密输入=明文密码密码=APP_ENCRYPTION_PASSWORD

我现在收到错误

密码加密是通过以下方式完成的

C:\Users\jonnie\Desktop\jasypt-1.9.0\bin>encrypt input=****** password=APP_ENCRYPTION_PASSWORD

----ENVIRONMENT-----------------

Runtime: Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM 20.12-b01



----ARGUMENTS-------------------

input: *******
password: APP_ENCRYPTION_PASSWORD



----OUTPUT----------------------

****encriptedPassword****

这个blog post有一个在使用 @Service 构建的 bean 上使用 @Value 的很好的示例。该测试使用@Autowire来设置@Service bean。
