SpringMVC与fastjson整合并同时解决中文乱码问题

abin — Sat, 12 Jan 2013 15:56:00 GMT

今天试着把SpringMVC与fastjson整合了下，经测试也能解决json含中文乱码的问题，特此分享之。我也是初用，详细文档请见官网。
public class MappingFastJsonHttpMessageConverter extends
        AbstractHttpMessageConverter {
    public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");

    private SerializerFeature[] serializerFeature;

    public SerializerFeature[] getSerializerFeature() {
        return serializerFeature;
    }

    public void setSerializerFeature(SerializerFeature[] serializerFeature) {
        this.serializerFeature = serializerFeature;
    }

    public MappingFastJsonHttpMessageConverter() {
        super(new MediaType("application", "json", DEFAULT_CHARSET));
    }

    @Override
    public boolean canRead(Class clazz, MediaType mediaType) {
        return true;
    }

    @Override
    public boolean canWrite(Class clazz, MediaType mediaType) {
        return true;
    }

    @Override
    protected boolean supports(Class clazz) {
        throw new UnsupportedOperationException();
    }

    @Override
    protected Object readInternal(Class clazz, HttpInputMessage inputMessage)
    throws IOException, HttpMessageNotReadableException {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int i;
        while ((i = inputMessage.getBody().read()) != -1) {
            baos.write(i);
        }
        return JSON.parseArray(baos.toString(), clazz);
    }

    @Override
    protected void writeInternal(Object o, HttpOutputMessage outputMessage)
    throws IOException, HttpMessageNotWritableException {
        String jsonString = JSON.toJSONString(o, serializerFeature);
        OutputStream out = outputMessage.getBody();
        out.write(jsonString.getBytes(DEFAULT_CHARSET));
        out.flush();
    }
}

SpringMVC关键配置：

                    WriteMapNullValue
                    QuoteFieldNames

package org.abin.lee.json;

public class Employee {
private String name="abin";
private double salary=1000;
private String sex="M";

public String getName() {
  return name;
}
public void setName(String name) {
  this.name = name;
}
public double getSalary() {
  return salary;
}
public void setSalary(double salary) {
  this.salary = salary;
}
public String getSex() {
  return sex;
}
public void setSex(String sex) {
  this.sex = sex;
}

}

package org.abin.lee.json;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;

public class JsonTest {
public static void main(String[] args) {
  GsonBuilder builder=new GsonBuilder();
  Gson gson=builder.create();
  String json1=gson.toJson(new Employee());
  System.out.println("json1="+json1);

  Employee json2=gson.fromJson(json1, Employee.class);
  System.out.println("json2="+json2);
  System.out.println(json2.getName());
  System.out.println(json2.getSalary());
  System.out.println(json2.getSex());
  System.out.println(json2.getClass());


}

}
