使用工具：Kaptcha 链接(需科学上网)

导入JAR包

地址

<!-- https://mvnrepository.com/artifact/com.github.penggle/kaptcha -->
<dependency>
    <groupId>com.github.penggle</groupId>
    <artifactId>kaptcha</artifactId>
    <version>2.3.2</version>
</dependency>

使用Bean注入进行配置

@Configuration
public class KaptchaConfig {

    @Bean
    public Producer kaptchaProducer(){
        Properties properties = new Properties();
        properties.setProperty("kaptcha.image.width","100");
        properties.setProperty("kaptcha.image.height","40");
        properties.setProperty("kaptcha.textproducer.font.size","32");
        properties.setProperty("kaptcha.textproducer.font.color","0,0,0");
        properties.setProperty("kaptcha.textproducer.char.string","0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ");
        properties.setProperty("kaptcha.textproducer.char.length","4");
        properties.setProperty("kaptcha.noise.impl","com.google.code.kaptcha.impl.NoNoise");
        
        DefaultKaptcha kaptcha = new DefaultKaptcha();
        Config config = new Config(properties);
        kaptcha.setConfig(config);
        return kaptcha;
    }
}
