[英]How to make jsonData case insensitive and in Spring MVC
春天的新人,
我正在嘗試訪問@RequestBody MYPOJO pojo
json 對象,該對象工作正常,但我的 json 數據需要與 pojo 中的變量名稱相同並且區分大小寫。 我從網上找到的最好的在這里,但沒有與我的項目同步,我正在使用 spring mvc。 那么如何使用 pojo 使我的 json 不區分大小寫呢?
我接收json的方式
@RequestMapping(value = "create", method = RequestMethod.POST)
public void createPost(HttpServletRequest req, HttpServletResponse resp, @Valid @RequestBody Post post,
Errors errors) throws CustomException, IOException {
json數據
function jsonForPost(isEdit, id) {
var post = {};
if (isEdit) {
post.id = id;
}
post.name = $("#name").val();
return JSON.stringify(post);
}
Spring Boot
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;
import com.fasterxml.jackson.databind.MapperFeature;
@Configuration
class Configs {
@Bean
public Jackson2ObjectMapperBuilderCustomizer initJackson() {
Jackson2ObjectMapperBuilderCustomizer c = new Jackson2ObjectMapperBuilderCustomizer() {
@Override
public void customize(Jackson2ObjectMapperBuilder builder) {
builder.featuresToEnable(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES);
}
};
return c;
}
}
Spring Boot
import java.util.List;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import com.fasterxml.jackson.databind.MapperFeature;
@Configuration
@EnableWebMvc
public class AppConfig extends WebMvcConfigurerAdapter {
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
builder.indentOutput(true);
builder.featuresToEnable(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES);
converters.add(new MappingJackson2HttpMessageConverter(builder.build()));
}
}
我有一個帶有變量名稱的 POJO:
public class Pox {
String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
和控制器:
@RequestMapping(value = "/create", method = RequestMethod.POST)
public void createPost(HttpServletRequest req, HttpServletResponse resp, @Valid @RequestBody Pox post,
Errors errors) {
System.out.println(post.getName());
}
我已經用Postman測試過:
姓名,姓名,姓名,姓名。
他們都工作了。
使用application.yml
文件的 springboot =>
spring:
jackson:
mapper:
accept-case-insensitive-properties: true
