SpringCloud项目jwt打包后运行报错 IDEA开发环境正常 ResourceServerConfig.java 系统默认编码格式GBK不同 开发环境为UTF-8 publicKey.txt

报错：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jwtAccessTokenConverter' defined in class path resource [com/qyj/config/ResourceServerConfig.class]: Invocation of init method failed; nested exception is java.lang.NullPointerException

at com.qyj.config.ResourceServerConfig.tokenStore(ResourceServerConfig.java:29) ~[ego-common-1.0.jar!/:1.0]

Caused by: java.lang.NullPointerException: null

原因：打包后触发bug，默认的编码格式不是UTF-8导致

方法一(无效 依然不行)：代码写死为UTF-8 防止环境不同而发生意外

//like12 find,bug,20220928,打包后运行报错,默认编码变为GBK,开发环境为UTF-8,导致解析配置文件失败
publicKey = FileUtil.readString(resource.getFile(), Charset.forName("UTF-8"));
//publicKey = FileUtil.readString(resource.getFile(), Charset.defaultCharset());

方法二(无效)：修改IDEA默认编码

全局修改编码格式

方法三：不再读取配置文件 直接写死在Java中

/**
 * 做公钥的解析
 *
 * @return
 */
@Bean
public JwtAccessTokenConverter jwtAccessTokenConverter() {
    JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
    /*// 设置公钥
    ClassPathResource resource = new ClassPathResource("publicKey.txt");
    String publicKey = null;
    try {
        //like12 find bug,20220928,打包后运行报错,默认编码变为GBK,开发环境为UTF-8(实测还是不行)
        //publicKey = FileUtil.readString(resource.getFile(), Charset.defaultCharset());
        publicKey = FileUtil.readString(resource.getFile(), Charset.forName("UTF-8"));
        System.out.println(publicKey);
    } catch (IOException e) {
        e.printStackTrace();
    }
    // 设置公钥
    jwtAccessTokenConverter.setVerifierKey(publicKey);*/

    //like12 find bug,20220928,打包后运行报错,common项目无法读取配置文件publicKey.txt,无法解决 只能写死在代码中了
    String publicKey = "-----BEGIN PUBLIC KEY-----\n" +
            "MIIBIj*****************************************S+1Gc\n" +
            "NwIDAQAB\n" +
            "-----END PUBLIC KEY-----";
    jwtAccessTokenConverter.setVerifierKey(publicKey);

    return jwtAccessTokenConverter;
}
