SpringBoot 自定义MessageConvert

创建一个MessageConvert类，实现HttpMessageConvert接口

简单实现，只完成写功能。其他默认false

package com.boot.converter;

import com.boot.pojo.Person;

import org.springframework.http.HttpInputMessage;

import org.springframework.http.HttpOutputMessage;

import org.springframework.http.MediaType;

import org.springframework.http.converter.HttpMessageConverter;

import org.springframework.http.converter.HttpMessageNotReadableException;

import org.springframework.http.converter.HttpMessageNotWritableException;

import java.io.IOException;

import java.io.OutputStream;

import java.util.List;

/**

public class MyMesConverter implements HttpMessageConverter<Person> {

    @Override

    public List<MediaType> getSupportedMediaTypes(Class<?> clazz) {

        return HttpMessageConverter.super.getSupportedMediaTypes(clazz);

    }

    @Override

    public boolean canRead(Class<?> clazz, MediaType mediaType) {

        return false;

    }

    @Override

    public boolean canWrite(Class<?> clazz, MediaType mediaType) {

        return clazz.isAssignableFrom(Person.class);

    }

    @Override

    public List<MediaType> getSupportedMediaTypes() {

        return MediaType.parseMediaTypes("application/x-z");

    }

    @Override

    public Person read(Class<? extends Person> clazz, HttpInputMessage inputMessage) throws IOException, HttpMessageNotReadableException {

        return null;

    }

    @Override

    public void write(Person person, MediaType contentType, HttpOutputMessage outputMessage) throws IOException, HttpMessageNotWritableException {

        String str = person.getUname()+";"+person.getAge()+";"+person.getPet();

        OutputStream body = outputMessage.getBody();

        body.write(str.getBytes());

    }

}

3.在自定义配置类中添加自定义的MessageConvert

 @Bean

    public WebMvcConfigurer webMvcConfigurer(){

        return new WebMvcConfigurer() {

            @Override

            public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {

                converters.add(new MyMesConverter());

            }

        };

    }
