Spring下 将父类属性转化为Json属性字段

使用Jackson的注解@JsonAutoDetect来标识bean属性自动检测级别
1. ANY:任何级别的字段都可以自动识别
2. NONE:所有字段都不可以自动识别
3. NON_PRIVATE:非private修饰的字段可以自动识别
4. PROTECTED_AND_PUBLIC:被protected和public修饰的字段可以被自动识别
5. PUBLIC_ONLY:只有被public修饰的字段才可以被自动识别
6. DEFAULT:同PUBLIC_ONLY

public class NetSearchRes {

protected int returnCode;

protected String keyWord;

public void setReturnCode(int returnCode) {
this.returnCode = returnCode;
}

public void setKeyWord(String keyWord) {
this.keyWord = keyWord;
}
}

import org.codehaus.jackson.annotate.JsonAutoDetect;
import com.ztx.bd.webservice.schemas.NetSearchRes;
@JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.PROTECTED_AND_PUBLIC)
public class Info extends NetSearchRes {
private String info;

private int infoType;

private String source;
public String getInfo() {
return info;
}
public void setInfo(String info) {
this.info = info;
}
public int getInfoType() {
return infoType;
}
public void setInfoType(int infoType) {
this.infoType = infoType;
}
public String getSource() {
return source;
}
public void setSource(String source) {
this.source = source;
}

}
