Question

错误日志：

org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'converter' defined in class path resource 
[...../spring/controller/PsvJackson2HttpMessageConverter.class]:
 No matching factory method found: factory bean 'psvJackson2HttpMessageConverter'; 
factory method 'converter()'. 
Check that a method with the specified name exists and that it is non-static.

这是配置类：

@Configuration
public class PsvJackson2HttpMessageConverter extends WebMvcConfigurationSupport {

     @Override
     public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
      converters.add(converter());
      converters.add(new ByteArrayHttpMessageConverter());
      converters.add(new StringHttpMessageConverter());
      super.addDefaultHttpMessageConverters(converters);
     }

     @Bean
     MappingJackson2HttpMessageConverter converter() {
         MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
         ObjectMapper objectMapper = new ObjectMapper();
         objectMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
         converter.setObjectMapper(objectMapper);
        return converter;
        }
}

不知道这里有什么问题。

以下是您可以做的事情：

创建一个配置类，用于注册/映射转换器。
创建自定义转换器类。

例如，这是配置类：

UITableView *tableView = (UITableView *)[self.view viewWithTag:1];

这是转换器类：

@EnableWebMvc
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureMessageConverters(final List<HttpMessageConverter<?>> converters) {
        converters.add(new CustomMappingJackson2HttpMessageConverter());
        super.configureMessageConverters(converters);
    }
}

配置MappingJacksonHttpMessageConverter获取BeanCreationException
