Intellij Plugin to generate Mapstruct mapper automatically

Mapstructor

This intellij plugin allows you to generate any MapStruct mapper, just by selecting any amount of code and executing an action.

Getting started

1. Get the plugin from the intellij plugin store.
2. Select any text
3. Executor the "MapStructor" Action
4. Select configs
5. Profit

Features

• Select any code and convert to mapstruct mapper
• Split each mapper into separate files
• Replace selected code with mapper initialization
• Generate interface or abstract class mapper
• Generate a test template for this mapper automatically

Examples

Before

var output = new Output1();
var output2Nested = new Output2();
var superNested = new Output3();

output2Nested.setNested1("1");
output2Nested.setNested2("1");
output2Nested.setOuterVariable(a);
superNested.setSuperNested1("1");
superNested.setSuperNested2("1");
superNested.setSuperOuterVariable(b);
output2Nested.setSuperNestedObject(superNested);
output.setInput1("test");
output.setInput5("abc");
output.setNestedThings(output2Nested);

return output;

After

@Mapper
public interface TestMapper {

    TestMapper INSTANCE = Mappers.getMapper(TestMapper.class);
    
    @Mapping(target = "superNested1", constant = "1")
    @Mapping(target = "superNested2", constant = "1")
    @Mapping(target = "superOuterVariable", source = "b")
    Output3 mapOutput3(String b);
    
    @Mapping(target = "input1", constant = "test")
    @Mapping(target = "input5", constant = "abc")
    @Mapping(target = "nestedThings", expression = "java(mapOutput2(b, a))")
    Output1 mapOutput1(String b, String a);
    
    @Mapping(target = "nested1", constant = "1")
    @Mapping(target = "nested2", constant = "1")
    @Mapping(target = "outerVariable", source = "a")
    @Mapping(target = "superNestedObject", source = "b")
    Output2 mapOutput2(String b, String a);

}
