JarCastingJackson datatype module to support JSON serialization/deserialization of Thrift objects
Maven dependency
To use module on Maven-based projects, use following dependency:
<dependency>
<groupId>io.github.artemy.osipov.thrift</groupId>
<artifactId>jackson-datatype-thrift</artifactId>
<version>0.1.0</version> // or any newer version
</dependency>
Usage
To use thrift datatype you will need to register the module:
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new ThriftModule());
For thrift with scheme:
struct SomeStruct {
1: string stringField
2: bool boolField
3: i32 intField
4: SomeEnum enumField
5: SomeInnerStruct complexField
}
struct SomeInnerStruct {
1: string f1
2: string f2
}
enum SomeEnum {
ENUM_1
ENUM_2
}
serialization will be:
SomeStruct thrift = new SomeStruct()
.setStringField("s1")
.setBoolField(true)
.setIntField(1)
.setEnumField(SomeEnum.ENUM_1)
.setComplexField(new SomeInnerStruct()
.setF1("f1")
.setF2("f2")
);
String json = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(thrift);
assert json.equals("""
{
"stringField": "s1",
"boolField": true,
"intField": 1,
"enumField": "ENUM_1",
"complexField": {
"f1": "f1",
"f2": "f2"
}
}""");
deserialization will be:
String json = """
{
"stringField": "s1",
"boolField": true,
"intField": 1,
"enumField": "ENUM_1",
"complexField": {
"f1": "f1",
"f2": "f2"
}
}""";
String thrift = mapper.readValue(json, SomeStruct.class);
assert thrift.equals(new SomeStruct()
.setStringField("s1")
.setBoolField(true)
.setIntField(1)
.setEnumField(SomeEnum.ENUM_1)
.setComplexField(
new SomeInnerStruct()
.setF1("f1")
.setF2("f2")
));
