| Modifier and Type | Method and Description |
|---|---|
Dict |
clone() |
protected String |
customKey(Object key)
自定义键
|
Dict |
filterNew(String... keys)
过滤Map保留指定键值对，如果键不存在跳过
|
<P,T> T |
get(SerFunction<P,T> func)
根据lambda的方法引用，获取
|
<T> T |
getBean(String attr)
获得特定类型值
|
<T> T |
getByPath(String expression)
通过表达式获取JSON中嵌套的对象
.表达式，可以获取Bean对象中的属性（字段）值或者Map中key对应的值 []表达式，可以获取集合等对象中对应index的值 表达式栗子： persion persion.name persons[3] person.friends[5].name |
<T> T |
getByPath(String expression,
Type resultType)
通过表达式获取JSON中嵌套的对象
.表达式，可以获取Bean对象中的属性（字段）值或者Map中key对应的值 []表达式，可以获取集合等对象中对应index的值 表达式栗子： persion persion.name persons[3] person.friends[5].name 获取表达式对应值后转换为对应类型的值 |
Object |
getObj(String key,
Object defaultValue)
获取Object属性值
|
static Dict |
of()
创建Dict
|
static Dict |
ofEntries(Map.Entry<String,Object>... pairs)
根据给定的Entry数组创建Dict对象
|
static Dict |
ofKvs(Object... keysAndValues)
根据给定的键值对数组创建Dict对象，传入参数必须为key,value,key,value...
|
static <T> Dict |
parse(T bean)
将PO对象转为Dict
|
<T> Dict |
parseBean(T bean)
将值对象转换为Dict
类名会被当作表名，小写第一个字母 |
<T> Dict |
parseBean(T bean,
boolean isToUnderlineCase,
boolean ignoreNullValue)
将值对象转换为Dict
类名会被当作表名，小写第一个字母 |
<T extends Dict> |
removeEqual(T dict,
String... withoutNames)
与给定实体对比并去除相同的部分
此方法用于在更新操作时避免所有字段被更新，跳过不需要更新的字段 version from 2.0.0 |
Dict |
removeNew(String... keys)
过滤Map去除指定键值对，如果键不存在跳过
|
Dict |
set(String attr,
Object value)
设置列
|
Dict |
setFields(SerSupplier<?>... fields)
通过lambda批量设置值
实际使用时，可以使用getXXX的方法引用来完成键值对的赋值： User user = GenericBuilder.of(User::new).with(User::setUsername, "hutool").build(); Dict.create().setFields(user::getNickname, user::getUsername); |
Dict |
setIgnoreNull(String attr,
Object value)
设置列，当键或值为null时忽略
|
<T> T |
toBean(Class<T> clazz)
填充Value Object对象
|
<T> T |
toBean(T bean)
转换为Bean对象
|
<T> T |
toBeanIgnoreCase(Class<T> clazz)
填充Value Object对象，忽略大小写
|
<T> T |
toBeanIgnoreCase(T bean)
转换为Bean对象
