java将Object转为实体类对象

用maven引入jackson-databind包

<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.11.3</version>
</dependency>

调用com.fasterxml.jackson.databind包下的ObjectMapper类中的convertValue方法。例：

    public Object toBody(Object param) {
        //ObjectMapper实例
        ObjectMapper objectMapper=new ObjectMapper();
        //转化为实体类PartnerRegisterBo
        PartnerRegisterBo bo = objectMapper.convertValue(param, PartnerRegisterBo.class);
        return bo;
    }
