從Spring 3.x遷移到4.x（未找到默認構造函數）

Question

我正在將Spring和Spring安全性從3.0.3更新到Spring 4.2.4和Spring Security 4.0.3的過程中。 我在使用..創建bean時遇到此錯誤，並且未找到ExceptionTranslationFilter類的默認構造函數。 此類具有兩個重載的構造函數，但未定義默認構造函數。 有什么辦法可以解決這個異常？

Answer 1

我想到了。 我不能直接給出答案，因為我必須更改配置文件中連接的許多bean。 在Spring 4.x中，我發現大多數setter注入已被替換為構造函數注入。

因此，對於我遇到錯誤的每個bean，都沒有找到bean創建或默認構造函數，我必須仔細閱讀文檔，以了解是否可以通過setter訪問屬性，或者是否在構造函數中傳遞了屬性，以及是否基於該屬性修改我的配置文件。 不好玩，但我經歷了。

從3.x到4.x的春季遷移非常有用

Answer 2

我遇到了幾乎相同的錯誤，在我的情況下，我根據Javadoc Spring Security 4.0.3指定了默認構造函數。RELEASEAPI-類ExceptionTranslationFilter

<b:bean id="etf" class="org.springframework.security.web.access.ExceptionTranslationFilter">
    <b:constructor-arg>
        <b:ref bean="preAuthEntryPoint" />
    </b:constructor-arg>
</b:bean>
