SpringBoot——读取配置文件@Value和@Configuration比较

1.@Configuration

package com.xgcd.springboot.bean;  import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.PropertySource; import org.springframework.stereotype.Component;  import java.util.Date; import java.util.List; import java.util.Map;  /**  * 将配置文件中的配置映射到这个组件中  *  * @ConfigurationProperties 告诉springboot将本类中的所有属性和配置文件中的相关配置进行绑定:  * prefix:配置文件中的哪个属性下的所有属性进行一一绑定  * 只有该组件是容器中的组件才可以发挥作用(提供@ConfigurationProperties功能)  * 可以在test中进行单元测试  */ @Component @ConfigurationProperties(prefix = "person") @PropertySource(value = {"classpath:application.properties"}, encoding = "utf-8") public class Person {     private String lastName;     private Integer age;     private boolean boss;     private Date birth;      private Map<String, Object> maps;     private List<Object> lists;     private Dog dog;      @Override     public String toString() {         return "Person{" +                 "lastName='" + lastName + '\'' +                 ", age=" + age +                 ", boss=" + boss +                 ", birth=" + birth +                 ", maps=" + maps +                 ", lists=" + lists +                 ", dog=" + dog +                 '}';     }      public String getLastName() {         return lastName;     }      public void setLastName(String lastName) {         this.lastName = lastName;     }      public Integer getAge() {         return age;     }      public void setAge(Integer age) {         this.age = age;     }      public boolean isBoss() {         return boss;     }      public void setBoss(boolean boss) {         this.boss = boss;     }      public Date getBirth() {         return birth;     }      public void setBirth(Date birth) {         this.birth = birth;     }      public Map<String, Object> getMaps() {         return maps;     }      public void setMaps(Map<String, Object> maps) {         this.maps = maps;     }      public List<Object> getLists() {         return lists;     }      public void setLists(List<Object> lists) {         this.lists = lists;     }      public Dog getDog() {         return dog;     }      public void setDog(Dog dog) {         this.dog = dog;     } }

2.@Value

二者比较

补充读取.properties文件乱码问题
