优化JaxRS/Jackson以排除空值,空列表,数组

在JAX-RS和Jackson中优化排除空值、空列表、数组的方法有以下几种：

使用Jackson的ObjectMapper配置排除空值、空列表、数组的选项：

ObjectMapper mapper = new ObjectMapper();
mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
mapper.setSerializationInclusion(JsonInclude.Include.NON_EMPTY);
mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

使用JAX-RS的XMLRootElement注解：

@XmlRootElement(name = "person", namespace = "http://example.com")
public class Person {
    private String name;
    private int age;
    private List<String> hobbies;

    // getters and setters
}

使用JAX-RS的JSONRootElement注解：

@JsonRootName(value = "person")
public class Person {
    private String name;
    private int age;
    private List<String> hobbies;

    // getters and setters
}

使用Jackson的ObjectWriter配置排除空值、空列表、数组的选项：

ObjectWriter writer = new ObjectMapper().writer();
writer.setSerializationInclusion(JsonInclude.Include.NON_NULL);
writer.setSerializationInclusion(JsonInclude.Include.NON_EMPTY);

使用JAX-RS的XMLMapper配置排除空值、空列表、数组的选项：

JAXRSSpecification.getInstance().setSerializationInclusion(JsonInclude.Include.NON_NULL);
JAXRSSpecification.getInstance().setSerializationInclusion(JsonInclude.Include.NON_EMPTY);

以上是排除空值、空列表、数组的一些常见方法，可以根据具体情况进行选择。
