ModelMapper 性能测试

ModelMapper 性能测试

这里只是给出性能测试，没有评判ModelMapper，项目中是否使用ModelMapper完全取决于个人

import org.modelmapper.ModelMapper;

/**

public class Test {
    public static void main(String[] args) {
        SourceModel sourceModel = new SourceModel();
        sourceModel.setId(1);
        sourceModel.setName("darling");
        sourceModel.setEmail("[e-mail]");
        Address address = new Address();
        address.setName("天宫市");
        sourceModel.setAddress(address);

        long start = System.currentTimeMillis();
        // 10w  9  10 0
//        setMethod(sourceModel);

        // 10w  432 10  65
        modelMapper(sourceModel);
        long end = System.currentTimeMillis();
        System.out.println("花费=======》"+(end-start));


    }

    private static void setMethod(SourceModel sourceModel) {
        for (int i = 0; i < 100000; i++) {
            TargetModel targetModel = new TargetModel();
            targetModel.setName(sourceModel.getName());
            targetModel.setEmail(sourceModel.getEmail());
            targetModel.setAddress(sourceModel.getAddress().getName());
        }
    }

    private static void modelMapper(SourceModel sourceModel) {
        ModelMapper modelMapper = new ModelMapper();
        for (int i = 0; i < 100000; i++) {
            TargetModel targetModel = modelMapper.map(sourceModel, TargetModel.class);
        }
    }
}
