在实现Jwt Spring Security实现时得到以下异常：“ java.lang.NoClassDefFoundError：无法初始化类javax.xml.bind.DatatypeConverterImpl。”在Spring Boot项目中

pom.xml中的依赖项如下：

详细的引导程序如下：

Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: 
Could not initialize class javax.xml.bind.DatatypeConverterImpl
] with root cause

在以下代码中生成JWT令牌时获取上述错误：

Jwts.builder().setClaims(claims).setExpiration(generateExpirationDate()).signWith(SignatureAlgorithm.HS512, secret).compact();

Answer 1

为将来参考，该解决方案添加了以下依赖项，以避免出现Java 11问题：

对于Maven项目：

<dependency> 
    <groupId>javax.xml.bind</groupId> 
    <artifactId>jaxb-api</artifactId>
    <version>2.1</version>
</dependency>

对于gradle项目：

compile 'javax.xml.bind:jaxb-api:2.1'

Answer 2

添加 JAXB API 依赖项解决了我的问题。

<!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version>
</dependency>

Answer 3

使用OpenJDK 11时，这对我也很好，而无需进行任何代码修改。

我在前端类上使用的是java.base。* enc / dec，而不是javax.xml.bind.DatatypeConverter，但是jjwt（0.9.0）在生成令牌时将其重新引入。

您的解决方案很好，不必将Xercesxml添加到我的pom.xml中，可能是因为我只是在做基本的jwt。

此致

Answer 4

是的，对我来说，添加 javax api 依赖项修复了我的错误。

compile 'javax.xml.bind:jaxb-api:2.1'

谢谢@Andrei

Answer 5

将此依赖项添加到 pom 文件对我有用：

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version><!--$NO-MVN-MAN-VER$-->
</dependency>
