Hibernate实体配置成WEB-INF(Hibernate entities configuration into WEB-INF)

 你有两个选择。 
 
 在getter或field上使用@JsonIgnore 
 
 带有@JsonIgnore注解的Sample类： 
 
class Sample {
    private String prop1;
    private String prop2;
    @JsonIgnore // could be here
    private String prop3;

    @JsonIgnore // could be here
    public String getProp3() {
        return prop3;
    }
}
 
 ObjectMapper使用Sample类中的注释： 
 
new ObjectMapper().writeValueAsString(new Sample("one", "two", "three"))
 
 第二个变体是使用自定义序列化器： 
 
 自定义序列化器： 
 
class SampleSerializer extends JsonSerializer<Sample> {

    @Override
    public void serialize(Sample sample, JsonGenerator jgen, SerializerProvider provider) throws IOException {
        jgen.writeStartObject();
        jgen.writeStringField("prop1", sample.getProp1());
        jgen.writeStringField("prop2", sample.getProp2());
        jgen.writeEndObject();
    }
}
 
 添加注释以使用自定义序列化器： 
 
@JsonSerialize(using = SampleSerializer.class)
class Sample {

    private String prop1;
    private String prop2;
    private String prop3;
}
 
 ObjectMapper使用Sample类中的注释： 
 
new ObjectMapper().writeValueAsString(new Sample("one", "two", "three"))
 
 如果您完全不使用Jackson批注，则可以将自定义序列化程序添加到ObjectMapper ： 
 
 Sample类不包含任何Jackson注释： 
 
class Sample {

    private String prop1;
    private String prop2;
    private String prop3;
}
 
 ObjectMapper应该知道如何序列化Sample类的方法： 
 
ObjectMapper mapper = new ObjectMapper();

SimpleModule module = new SimpleModule();
module.addSerializer(Sample.class, new SampleSerializer());
mapper.registerModule(module);

mapper.writeValueAsString(new Sample("one", "two", "three"));

You have two options.
 
Use @JsonIgnore on getter or field
 
Sample class with @JsonIgnore annotation:
 
class Sample {
    private String prop1;
    private String prop2;
    @JsonIgnore // could be here
    private String prop3;

    @JsonIgnore // could be here
    public String getProp3() {
        return prop3;
    }
}
 
ObjectMapper use annotations from the Sample class:
 
new ObjectMapper().writeValueAsString(new Sample("one", "two", "three"))
 
Second variant, is to use custom serializer:
 
Custom serializer:
 
class SampleSerializer extends JsonSerializer<Sample> {

    @Override
    public void serialize(Sample sample, JsonGenerator jgen, SerializerProvider provider) throws IOException {
        jgen.writeStartObject();
        jgen.writeStringField("prop1", sample.getProp1());
        jgen.writeStringField("prop2", sample.getProp2());
        jgen.writeEndObject();
    }
}
 
Add annotation to use custom serializer:
 
@JsonSerialize(using = SampleSerializer.class)
class Sample {

    private String prop1;
    private String prop2;
    private String prop3;
}
 
ObjectMapper use annotations from the Sample class:
 
new ObjectMapper().writeValueAsString(new Sample("one", "two", "three"))
 
If you do not use Jackson annotations for the class at all, you could add your custom serializer to ObjectMapper:
 
Sample class does not contain any Jackson annotation:
 
class Sample {

    private String prop1;
    private String prop2;
    private String prop3;
}
 
ObjectMapper should know about the way how to serialize Sample class:
 
ObjectMapper mapper = new ObjectMapper();

SimpleModule module = new SimpleModule();
module.addSerializer(Sample.class, new SampleSerializer());
mapper.registerModule(module);

mapper.writeValueAsString(new Sample("one", "two", "three"));
