public class SampleTest {
private transactable tt;
public transactable getTt() {
return tt;
}
public void setTt(transactable tt) {
this.tt = tt;
}
}
主类如下所示：请参考我正在使用的罐子
public class transactable {
private String transactable;
private String value;
private String departmentid;
public String getTransactable() {
return transactable;
}
public void setTransactable(String transactable) {
this.transactable = transactable;
}
public String getDepartmentid() {
return departmentid;
}
public void setDepartmentid(String departmentid) {
this.departmentid = departmentid;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
上述类的输出是
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.ArrayList;
import java.util.List;
public class TestString {
public static void main(String[] args) {
TestString test = new TestString();
test.substring();
}
private void substring() {
List<String> test = new ArrayList<>();
test.add("test:111111");
test.add("test:1122222");
List<SampleTest> sss = new ArrayList<>();
SampleTest s1 = new SampleTest();
transactable t1 = new transactable();
t1.setTransactable("transactable1");
t1.setValue("true1");
t1.setDepartmentid("1111");
s1.setTt(t1);
sss.add(s1);
SampleTest s2 = new SampleTest();
transactable t2 = new transactable();
t2.setTransactable("transactable2");
t2.setValue("true2");
t2.setDepartmentid("2222");
s2.setTt(t2);
sss.add(s2);
final ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(JsonGenerator.Feature.ESCAPE_NON_ASCII,true);
String s = null;
try {
s = objectMapper.writeValueAsString((sss));
System.out.println(s);
} catch (JsonProcessingException e) {
e.printStackTrace();
}
}
}
预期结果是：
[{"tt":{"transactable":"transactable1","value":"true1"}},{"tt":{"transactable":"transactable2","value":"true2"}}]
父对象“ tt”需要附加其他字符串示例“ 4300”，“ 5600”。 请告知我该怎么做。
感谢您的帮助。
