When using the following code to return the Demo entity, there is a problem of Chinese garbled characters. The code is as follows:
APP startup class:
@SpringBootApplication
@ComponentScan("soringboot.hello")
public class APP extends WebMvcConfigurerAdapter{
public static void main(String[] args) {
SpringApplication.run(APP.class, args);
}
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
super.extendMessageConverters(converters);
// define convert
FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
FastJsonConfig config = new FastJsonConfig();
config.setSerializerFeatures(SerializerFeature.PrettyFormat);
fastJsonHttpMessageConverter.setFastJsonConfig(config);
converters.add(fastJsonHttpMessageConverter);
}
}
Demo type:
public class Demo {
private int id;
private String name;
//com.alibaba.fastjson.annotation.JSONField;
@JSONField(format="yyyy-MM-dd HH:mm")
private Date createTime;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
}
controller class:
@RestController
public class HelloContorller {
@RequestMapping("/getDemo1")
public Demo getDemo1()
{
Demo demo = new Demo();
demo.setId(1);
demo.setName("Quality Youth");
demo.setCreateTime(new Date());
return demo;
}
}
When accessing getDemo1 through a browser, the following phenomenon occurs:
{"createTime":"2018-04-22 13:23","id":1,"name":"浼樿川闈掑勾"}
That is: high-quality young people have become
Solving the problem is the most important, and the code is directly attached below:
@SpringBootApplication
@ComponentScan("soringboot.hello")
public class APP extends WebMvcConfigurerAdapter{
public static void main(String[] args) {
SpringApplication.run(APP.class, args);
}
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
super.extendMessageConverters(converters);
// define convert
FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
FastJsonConfig config = new FastJsonConfig();
config.setSerializerFeatures(SerializerFeature.PrettyFormat);
// handle Chinese garbled characters
// Create a collection of MediaTypes
List<MediaType> supportedMediaTypes = new ArrayList<MediaType>();
// Set the encoding format to UTF8
supportedMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
// Assign the supportedMediaTypes object to the SupportedMediaTypes property of fastJsonHttpMessageConverter
fastJsonHttpMessageConverter.setSupportedMediaTypes(supportedMediaTypes );
fastJsonHttpMessageConverter.setFastJsonConfig(config);
converters.add(fastJsonHttpMessageConverter);
}
}
Visit the original path again, the effect is as follows:
{
"createTime":"2018-04-22 13:28",
"id":1,
"name":"优质青年"
}
This solved the problem. Of course, if it is the fastjson conversion method implemented by @Bean, the processing method is the same, such as:
@SpringBootApplication
@ComponentScan("soringboot.hello")
public class APP extends WebMvcConfigurerAdapter{
public static void main(String[] args) {
SpringApplication.run(APP.class, args);
}
/*@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
super.extendMessageConverters(converters);
// define convert
FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
FastJsonConfig config = new FastJsonConfig();
config.setSerializerFeatures(SerializerFeature.PrettyFormat);
// handle Chinese garbled characters
// Create a collection of MediaTypes
List<MediaType> supportedMediaTypes = new ArrayList<MediaType>();
// Set the encoding format to UTF8
supportedMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
// Assign the supportedMediaTypes object to the SupportedMediaTypes property of fastJsonHttpMessageConverter
fastJsonHttpMessageConverter.setSupportedMediaTypes(supportedMediaTypes );
fastJsonHttpMessageConverter.setFastJsonConfig(config);
converters.add(fastJsonHttpMessageConverter);
}*/
@Bean
public HttpMessageConverters fastJsonHttpMessageConverters()
{
FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter();
FastJsonConfig config = new FastJsonConfig();
config.setSerializerFeatures(SerializerFeature.PrettyFormat);
// handle Chinese garbled characters
// Create a collection of MediaTypes
List<MediaType> supportedMediaTypes = new ArrayList<MediaType>();
// Set the encoding format to UTF8
supportedMediaTypes.add(MediaType.APPLICATION_JSON_UTF8);
// Assign the supportedMediaTypes object to the SupportedMediaTypes property of fastJsonHttpMessageConverter
fastJsonHttpMessageConverter.setSupportedMediaTypes(supportedMediaTypes );
fastJsonHttpMessageConverter.setFastJsonConfig(config);
return new HttpMessageConverters(fastJsonHttpMessageConverter);
}
}
