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>
