无法获取全局转换器工厂Bean

[hunao0221]

在配置文件中配置了转换工厂为fastjson的Retrofit2ConverterFactory

retrofit:
  # 全局转换器工厂
  global-converter-factories:
    - com.github.lianjiatech.retrofit.spring.boot.core.BasicTypeConverterFactory
    - com.alibaba.fastjson.support.retrofit.Retrofit2ConverterFactory

并且注册了Bean

    @Bean
    public Converter.Factory converterFactory() {
        return Retrofit2ConverterFactory.create();
    }

应用启动时警告日志，提示找不到Retrofit2ConverterFactory Bean

如果找不到Bean的话，retrofit-spring-boot-starter是会用反射的方式获取的，因此这里并不影响功能。 不过不确定这是不是一个bug，请确认。

看源码找到解决方法，应该返回具体的实现，而不是接口

    @Bean
    public Retrofit2ConverterFactory converterFactory() {
        return Retrofit2ConverterFactory.create();
    }
