如何在Spring中注册自定义类型转换器？

import org.springframework.core.convert.converter.Converter;

public class CustomTypeConverter implements Converter<SourceType, TargetType> {
    @Override
    public TargetType convert(SourceType source) {
        // 实现源类型到目标类型的转换逻辑
    }
}

import org.springframework.context.annotation.Configuration;

@Configuration
public class AppConfig {
    // 配置类中的其他Bean定义
}

import org.springframework.context.annotation.Bean;

@Configuration
public class AppConfig {
    @Bean
    public CustomTypeConverter customTypeConverter() {
        return new CustomTypeConverter();
    }

    // 配置类中的其他Bean定义
}

import org.springframework.core.convert.ConversionService;
import org.springframework.core.convert.support.DefaultConversionService;

public class Main {
    public static void main(String[] args) {
        AppConfig appConfig = new AppConfig();
        ConversionService conversionService = new DefaultConversionService();
        conversionService.addConverter(appConfig.customTypeConverter());

        // 使用自定义类型转换器进行类型转换
        TargetType target = conversionService.convert(source, TargetType.class);
    }
}
