Java error: java.lang.ClassNotFoundException:

Question

首先声明我不是 Java 开发人员，而是需要为项目利用一小部分 Java 代码的 Python 开发人员。 :-)

也就是说，我收到以下错误：

Caused by: java.lang.ClassNotFoundException: CustomSecurePropertyPlaceholderModule

使用以下代码：

<?xml version="1.0" encoding="UTF-8"?>

我已确保 src/main/java 在运行配置中的构建路径上（文件 CustomSecurePropertyPlaceholderModule 位于此处）。我还看到 shared_resources/target/classes 也被设置为运行配置中的输出文件夹。知道为什么我仍然收到此错误吗？

Answer 1

在Java中，class通常是在包中。

喜欢，com.yourself.CustomSecurePropertyPlaceholderModule

尝试将您的 class（希望您有）放入 src/main/java/com/yourself，并在前面添加 package com.yourself；并使用

<spring:bean id="secure-property-placeholder" class="com.yourself.CustomSecurePropertyPlaceholderModule">
