我有2个弹簧启动应用程序（maven项目），其中包含＆＃34; spring-boot-starter-actuator＆＃34;依赖性，用于检查每个应用程序的运行状况。在tomcat服务器中部署这两个应用程序时，我得到以下异常 -

有人可以帮我解决这个例外吗？提前谢谢。

您可以在application.properties中使用以下属性为每个应用程序配置JMX域（例如，将应用程序名称用作域）：

import numpy as np
import matplotlib.pylab as plt

A = np.random.random((20,20))
B = np.random.random((20,20))

array_1 = A/B    # A and B are 2 arrays, same shape etc ..

# Mask the array with the required limits
array_1 = np.ma.masked_where(array_1 > 1, array_1)

fig1 = plt.figure()
ax1  = plt.subplot(111)
fig_step1 = ax1.imshow(array_1, interpolation='nearest')
fig1.colorbar(fig_step1,ax=ax1)
ax1.set_xlabel("X (arcmin)")
ax1.set_ylabel("Y (arcmin)")
ax1.set_title("No limits, but masked")

这将为Spring添加的所有JMX端点配置域。

spring.jmx.default-domain=applicationname

这仅为执行器端点配置JMX域。

这将防止在不同的应用程序中具有相同名称的JMX bean的冲突，因为域将被添加到JMX名称。
