Feign调用无法解析 IPage包裹的数据问题

Feign调用无法解析 IPage包裹的数据，目前解决方案有两种，一种是转Page，另一种是序列化。

一、转Page传递

// api接口
@PostMapping(value = "/queryEnterprise")
public Result<Page<StudentEnterprise>> queryEnterprise(@RequestBody StuEnterPriseQo qoo) {
		StudentEnterprise qo = new StudentEnterprise().setDeleted(0);
		if(Objects.nonNull(qoo.getName())){
			qo.setName(qoo.getName());
		}
		QueryWrapper<StudentEnterprise> queryWrapper = QueryGenerator.initQueryWrapper(qo, null);
		Page<StudentEnterprise> page = new Page<>(qoo.getPageNo(), qoo.getPageSize());
		Page<StudentEnterprise> pageList = studentEnterpriseService.page(page, queryWrapper);
		return Result.OK(pageList);
}
//feign调用
@PostMapping("/studentEnterprise/queryEnterprise")
@ApiOperation(value = "企业信息列表", notes = "企业信息列表")
JsonResult<Page<StudentEnterpriseVo>> queryEnterprise(@RequestBody StuEnterPriseQo qo);

二、序列化，在config文件夹添加如下代码。

import com.baomidou.mybatisplus.core.metadata.IPage;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.deser.std.StdDeserializer;

import java.io.IOException;

public class IPageDeserializer extends StdDeserializer<IPage> {
    protected IPageDeserializer(Class<?> vc) {
        super(vc);
    }
    

    @Override
    public IPage deserialize(JsonParser p, DeserializationContext ctxt) throws IOException {
        JsonNode node = p.getCodec().readTree(p);
        String s  = node.toString();
        ObjectMapper om = new ObjectMapper();
        Page page = om.readValue(s,Page.class);
        return page;
    }

}

import com.baomidou.mybatisplus.core.metadata.IPage;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.module.SimpleModule;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

import java.util.Arrays;
import java.util.List;

@Configuration
public class WebDataConvertConfig extends WebMvcConfigurationSupport {

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(mappingJackson2HttpMessageConverter());
        super.configureMessageConverters(converters);
    }
     
    @Bean
    public MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
     
        SimpleModule module = new SimpleModule();
        module.addDeserializer(IPage.class, new IPageDeserializer(IPage.class));
        mapper.registerModule(module);
     
        converter.setSupportedMediaTypes(Arrays.asList(MediaType.APPLICATION_JSON, MediaType.APPLICATION_JSON_UTF8, MediaType.APPLICATION_OCTET_STREAM));
        converter.setObjectMapper(mapper);
     
        return converter;
    }

}
