Spring請求參數（參數對象的屬性對象）converter

問題描述：請求參數address,接受請求參數用people接受（address是個對象，也是people的一個屬性）

一、entity類創建 （people、address）

@Data
public class People {
    
    private String name;
    private Date sourcedate;
    private Address address;

}

public class Address {
    
    private String homeAddress;
}

二、類型轉換器的 AddressConverter

public class AddressConverter implements Converter<String,Address>{


    @Override
    public Address convert(String source) {
        return new Address(source);
    }

}

三、將類型轉換器添加到spring中

@Configuration
public class WebConfiguration {
    
    @Bean
    public GenericConversionService getGenericConversionService(@Autowired GenericConversionService conversionService) {
        conversionService.addConverter(new AddressConverter());
        System.out.println("類型轉換已加入！");
        return conversionService;
        
    }
}

四、controller

@Controller
public class HelloController {
    @RequestMapping("/test")
    @ResponseBody
    public String hello( People people) {
        
        return "===="+people.getAddress();
    }
}

五、測試
