package com.limi.springboottest2.entity;
import lombok.AllArgsConstructor;

}

Entity1

package com.limi.springboottest2.entity;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.util.List;
import java.util.Map;
@ConfigurationProperties(prefix = "entity1")
@Data
@AllArgsConstructor
@NoArgsConstructor
@Component
public class Entity1 {
    private Double number;
    private List<String> array;
    private User user;
    private Map<String, Integer> map;
    private String str0;
    private String str1;
    private String str2;
}

application.yml

entity1:
number: 11
array: ["apple", "peach", "orange"]
user: {userName: "lily", }
map: {"Math": 100,"English": 98,"Art": 8}
#對比字符串變量不使用引號、使用單引號、雙引號的區(qū)別
str0: \n 666
str1: '\n 666'
str2: "\n 666"

HelloController

package com.limi.springboottest2.controller;
import com.limi.springboottest2.entity.Entity1;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HelloController {
    @Autowired
    private Entity1 entity1;
    @GetMapping("/test1")
    @ResponseBody
    void test1() {
        System.out.println(entity1);
    }
}

測試結(jié)果

可以看到

不使用引號和使用單引號的字符串: n 666 中的\n是直接輸出\n
使用雙引號的字符串: \n 666 中的\n是輸出為換行符

4.開啟補全提示

就是下圖的效果

自定義的類和配置文件綁定一般沒有提示。若要提示，添加如下依賴：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>
<!-- 下面插件作用是工程打包時，不將spring-boot-configuration-processor打進包內(nèi)，讓其只在編碼的時候有用 -->
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <excludes>
                    <exclude>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-configuration-processor</artifactId>
                    </exclude>
                </excludes>
            </configuration>
        </plugin>
    </plugins>
</build>
