@jsonignore 在哪个jar

Posted 2023-05-01

参考技术A public class JackJsonTest
public static void main(String[] args) throws IOException
User user = new User("abc", "id", 10);
ObjectMapper objectMapper = new ObjectMapper();
String json = objectMapper.writeValueAsString(user);
System.out.println(json);
User jsonUser = objectMapper.readValue(json, User.class);
System.out.println(jsonUser.getAge());
List<User> list = new ArrayList<User>();
list.add(new User("abc1", "id1", 101));
list.add(new User("abc2", "id2", 102));
list.add(new User("abc3", "id3", 103));
String listJson = objectMapper.writeValueAsString(list);
System.out.println(listJson);
List<User> beanList = objectMapper.readValue(listJson, new TypeReference<List<User>>()
);
for (User jsonUserList : beanList)
System.out.println(jsonUserList);





class User

private String name;

private String id;
private Integer age;

@JsonProperty(value = "aaa")
public String getName()
return name;


@JsonProperty(value = "aaa")
public void setName(String name)
this.name = name;

@JsonIgnore
public String getId()
return id;


public void setId(String id)
this.id = id;


public Integer getAge()
return age;


public void setAge(Integer age)
this.age = age;


public User()


public User(String name, String id, Integer age)
this.name = name;
this.id = id;
this.age = age;


@Override
public String toString()
return "User" +
"name='" + name + '\'' +
", id='" + id + '\'' +
", age=" + age +
'';

查找在哪个jar中定义了类

Useful when you have to deal with ClassNotFoundException. The command looks for all jar in the current directory and any sub-directory, and checks if the jar contains the specified class. The command lists all matching jars.

find -name "*.jar" -exec grep "CLASSNAME" {} \;
find -name "*.jar" -exec grep "org/junit/runners/Parameterized.class" {} \;
