無法自省類 [org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration]

Question

我使用 spring boot 2.1.1 創建了一個項目，當我嘗試解除它時，我收到以下錯誤：

Answer 1

如果您在 POM 中對 spring-boot-starter-tomcat 有以下依賴關系，請刪除它的范圍部分。

現存的：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

新的：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>

Answer 2

該錯誤很有幫助，因為它找不到所需的類javax.servlet.Filter並且擁有此類的常用方法是通過此依賴項：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <scope>provided</scope>
        </dependency>

最終拉入org.apache.tomcat.embed:tomcat-embed-core

我們在本地看到了這一點，因為當從 Intellij 運行 Spring Boot 應用程序時，我們沒有在“運行/調試配置”中勾選“包含具有“已提供”范圍的依賴項”選項。

Answer 3

我認為這種依賴：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

與此發生沖突：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <type>jar</type>
</dependency>

為什么需要最后一個？ 我認為你不需要它，因為你已經有了安全啟動器，所以刪除它。

Answer 4

嘗試將此添加到您的 pom.xml：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>4.0.1.RELEASE</version>
</dependency>

它幫助了我。

Answer 5

這是在嘗試引用不存在的類時引起的。 添加此依賴項修復了我的錯誤：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
</dependency>

在我的日志底部出現了：

Caused by: java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.security.servlet.SpringBootWebSecurityConfiguration$SecurityFilterChainConfiguration
Caused by: java.lang.IllegalStateException: Failed to introspect Class [org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration] from ClassLoader [jdk.internal.loader.ClassLoaders$AppClassLoader@73d16e93]
Caused by: java.lang.NoClassDefFoundError: org/springframework/security/web/SecurityFilterChain
Caused by: java.lang.ClassNotFoundException: org.springframework.security.web.SecurityFilterChain

顯示org.springframework.security.web.SecurityFilterChain類不存在。

所以在一些谷歌搜索中，我發現該類存在於spring-security-web存儲庫中。 將其添加到pom.xml中的依賴項后，瞧，下一次構建成功通過。

Answer 6

我今天遇到了同樣的問題。 事實證明，這個問題是由於主啟動類沒有放在代碼的最外層引起的。 確保您已在正確的位置定義了啟動類。
