记录Feign调用时对LocalDateTime的处理

feign api调用参数类型为LocalDateTime一直报错，类型转换错误

简单记录一下解决方式吧

调用方

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jdk8.Jdk8Module;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import com.fasterxml.jackson.module.paramnames.ParameterNamesModule;

@Configuration
public class LocalDateTimeConfig {
    
    @Bean(name = "mapperObject")
    public ObjectMapper getObjectMapper() {
        return new ObjectMapper().registerModule(new ParameterNamesModule()).registerModule(new Jdk8Module())
                .registerModule(new JavaTimeModule());
    }


}

服务提供方

import java.time.LocalDateTime;

import javax.annotation.PostConstruct;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.support.GenericConversionService;
import org.springframework.web.bind.support.ConfigurableWebBindingInitializer;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;

@Configuration
public class WebConfigBeans {
    @Autowired
    private RequestMappingHandlerAdapter handlerAdapter;
    
    @PostConstruct
    public void initEditableValidation() {
        ConfigurableWebBindingInitializer initializer = (ConfigurableWebBindingInitializer) handlerAdapter
            .getWebBindingInitializer();
        if (initializer.getConversionService() != null) {
                GenericConversionService genericConversionService = (GenericConversionService) initializer
                        .getConversionService();
                genericConversionService.addConverter(String.class, LocalDateTime.class, new String2DateConverter());
            }
        }
    
}

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

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

public class DateConverter implements Converter<String, LocalDateTime> {

    @Override
    public LocalDateTime convert(String source) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        return LocalDateTime.parse(source,formatter);
    }
    
}
