Jar包中读取微信支付证书

通过this.getClass().getResourceAsStream()读入数据

KeyStore keyStore = KeyStore.getInstance("PKCS12");

keyStore.load(instream, mchId.toCharArray());

报错：

DerInputStream.getLength(): lengthTag=111, too big. 

原因：打包时证书文件被篡改

解决办法：

1.spring-boot

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <excludes>
                <!--排除证书文件-->
                <exclude>**/*.p12</exclude>
            </excludes>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <!--避免证书文件被篡改-->
            <filtering>false</filtering>
            <includes>
                <include>**/*.p12</include>
            </includes>
        </resource>
    </resources>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

2.apache

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <configuration>
        <encoding>UTF-8</encoding>
        <!-- 过滤后缀为p12的证书文件 -->
        <nonFilteredFileExtensions>
            <nonFilteredFileExtension>p12</nonFilteredFileExtension>
        </nonFilteredFileExtensions>
    </configuration>
</plugin>
