spring-boot配置属性注入到Bean

1.在属性文件中配置book实体 

2.创建配置属性对应实体类与控制器 

3.输出实体时乱码

在属性配置文件中加入

spring.http.encoding.force=true

spring.http.encoding.charset=UTF-8

spring.http.encoding.enabled=true

server.tomcat.uri-encoding=UTF-8

可解决乱码问题

指定单个属性文件乱码时在要该属性文件的中加入： 

spring.http.encoding.force=true

spring.http.encoding.charset=UTF-8

spring.http.encoding.enabled=true

这里指定的属性文件为resources目录下的newbook.properties文件 

其实application.properties与application.yaml配置文件是可以共存的，properties文件的优先级高来yaml

下图为同时使用properties与yaml

实体类代码： 

package org.sang.model;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "book")
public class Book {
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public Float getPrice() {
        return price;
    }

    public void setPrice(Float price) {
        this.price = price;
    }

    private String name;
    private String author;
    private Float price;

    @Override
    public String toString() {
        return "Book{" +
                "name='" + name + '\'' +
                ", author='" + author + '\'' +
                ", price=" + price +
                '}';
    }
}

配置代码：

server.port=8888
server.errorpath=/error
server.servlet.session.timeout=30
server.tomcat.uri-encoding=utf-8
server.tomcat.max_threads=500
server.tomcat.basedir=/log
spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.ssl.key-store=metrox.p12
server.ssl.key-alias=tomcathttps
server.ssl.key-store-password=123456
book.name=三国演义
book.author=罗贯中
book.price=38

控制器代码

package org.sang.controller;

import org.sang.model.Book;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class BookController {
    @Autowired
    Book book;
    @GetMapping("/book")
    public String book(){
        return book.toString();
    }
}
