Java PropertyUtils類使用實例

實例1: loadYaml

import org.yaml.snakeyaml.introspector.PropertyUtils; //導入依賴的package包/類private Object loadYaml(File omapfile) throws IOException {    FileReader reader = new FileReader(omapfile);    try {        Constructor constructor = new Constructor();        PropertyUtils putils = new PropertyUtils();        putils.setSkipMissingProperties(true);        constructor.setPropertyUtils(putils);        Yaml yaml = new Yaml(constructor);        return yaml.load(reader);    } catch (Throwable t) {        throw new RuntimeException("Error loading yaml from: " + omapfile.getAbsolutePath() + "\n" + t.getMessage(), t);    } finally {        try {            reader.close();        } catch (IOException e) {            e.printStackTrace();        }    }} 

實例2: loadYaml

import org.yaml.snakeyaml.introspector.PropertyUtils; //導入依賴的package包/類private Object loadYaml(File file) throws FileNotFoundException {    FileReader reader = new FileReader(file);    try {        Constructor constructor = new Constructor();        PropertyUtils putils = new PropertyUtils();        putils.setSkipMissingProperties(true);        constructor.setPropertyUtils(putils);        Yaml yaml = new Yaml(constructor);        return yaml.load(reader);    } catch (Throwable t) {        throw new RuntimeException("Error loading yaml from: " + file.getAbsolutePath() + "\n" + t.getMessage(), t);    } finally {        try {            reader.close();        } catch (IOException e) {            e.printStackTrace();        }    }} 

實例3: newYaml

import org.yaml.snakeyaml.introspector.PropertyUtils; //導入依賴的package包/類public static Yaml newYaml() {  PropertyUtils propertyUtils = new AdvancedPropertyUtils();  propertyUtils.setSkipMissingProperties(true);  Constructor constructor = new Constructor(Federations.class);  TypeDescription federationDescription = new TypeDescription(Federations.class);  federationDescription.putListPropertyType("federatedMetaStores", FederatedMetaStore.class);  constructor.addTypeDescription(federationDescription);  constructor.setPropertyUtils(propertyUtils);  Representer representer = new AdvancedRepresenter();  representer.setPropertyUtils(new FieldOrderPropertyUtils());  representer.addClassTag(Federations.class, Tag.MAP);  representer.addClassTag(AbstractMetaStore.class, Tag.MAP);  representer.addClassTag(WaggleDanceConfiguration.class, Tag.MAP);  representer.addClassTag(YamlStorageConfiguration.class, Tag.MAP);  representer.addClassTag(GraphiteConfiguration.class, Tag.MAP);  DumperOptions dumperOptions = new DumperOptions();  dumperOptions.setIndent(2);  dumperOptions.setDefaultFlowStyle(FlowStyle.BLOCK);  return new Yaml(constructor, representer, dumperOptions);} 

實例4: testErrorMessage

import org.yaml.snakeyaml.introspector.PropertyUtils; //導入依賴的package包/類public void testErrorMessage() throws Exception {        BeanA1 b = new BeanA1();        b.setId(2l);        b.setName("name1");        Constructor c = new Constructor();        Representer r = new Representer();        PropertyUtils pu = new PropertyUtils();        c.setPropertyUtils(pu);        r.setPropertyUtils(pu);        pu.getProperties(BeanA1.class, BeanAccess.FIELD);        Yaml yaml = new Yaml(c, r);        // yaml.setBeanAccess(BeanAccess.FIELD);        String dump = yaml.dump(b);        BeanA1 b2 = (BeanA1) yaml.load(dump);        assertEquals(b.getId(), b2.getId());        assertEquals(b.getName(), b2.getName());    }
