Springboot Solr 配置和使用目录.png
一、springboot+solr简单测试
1、创建springboot项目和测试代码
环境：springboot+solr+swagger2
说明：在项目此处连接的是solr中core库，方式二创建的

添加swagger2配置
创建文件夹：config\Swagger2Config.java

return new ApiInfoBuilder()

然后启动该项目之后，进入项目地址：
http://localhost:8080/swagger-ui.html 执行-即可测试插入索引操作。
插入成功之后，访问：
http://127.0.0.1:8983/solr/#/
在solr管理界面的左下方有一个下拉框，选择你创建的core之后，再选择Query，往下拖到最后，点击Execute Query即可看见你刚才插入的索引。
solr效果.png
其他问题：
刚才我们代码中插入了两个列(id、name)，如果你想新增一个列，比如名称叫做age，然后启动项目，在插入索引，在solr管理平台中就看不见这个列名和列对应的值，原因是id、name这两列在solr中已经默认配置了。这种情况解决方式如下：
在你创建的core文件夹下面，打开conf文件夹，修改里面的managed-schema文件，修改地点如下：
# 132行后面增加(后面这几行随意位置增加就可以)
修改完成之后重启solr，然后重新插入索引就可以成功操作了。
再测试：
SolrController.java
SolrInputDocument doc = new SolrInputDocument();
doc.setField("id", idStr); //id是默认配置，在你创建的core文件夹下面，打开conf文件夹，修改里面的managed-schema文件
doc.setField("name", content); // name是默认配置
doc.setField("age","23"); //自定义配置：在你创建的core文件夹下面，打开conf文件夹，修改里面的managed-schema文件，添加列 age
效果图：

二、升级版测试
添加配置：
pom.xml
org.springframework.boot

org.json
json
20160810
net.sf.json-lib
json-lib
2.4
jdk15
com.alibaba
fastjson
1.2.4
*.yml文件配置 solr
spring:
data:
solr:
#后面这个core就是文件夹的名称，这里也可以不用写这个，如果这里不指定core，那么在代码中使用的时候，就需要指定core。
#host: http://127.0.0.1:8983/solr/core
#代码中可以指定core的地方有注释可以看

3、Solr加用户后密码的配置
具体配置用户验证参考：[Solr 配置用户登录验证.md](Solr 配置用户登录验证.md)
springboot通过solr地址中加入用户名密码的方式连接，地址如下：
*.yml文件
spring:
data:
solr: # 全文检索
# solr加上了用户名密码访问条件，参数中并没有地方设置username和password，那应该怎么办?
host: http://user:[email protected]:8983/solr
